What Does GSM Mean?

The meaning of GSM is the Global System for Mobile Communications, and it is the most widely used network system in the world. In fact, only countries like Russia and the USA have moved on from GSM to other network systems. Originally, GSM meant Groupe Spécial Mobile, but the acronym was updated when cell service became commercialized in 1991.

GSM network is an international standard that applies Time Division Multiple Access (TDMA), which assigns time slots to various conversation streams. These slots are alternated in sequence, with a very short interval between each conversation. In those intervals, phones can transmit phone-specific information. Every GSM phone must have a SIM card (Subscriber Identification Module), as it shows the network that users are connected to.

The SIM card is pivotal to the proper function of GSM networks. It is your SIM card that contains your network identification, address book information, and service subscription details. Through the SIM card, every phone conversation is assigned a time slot, and you can find out the network services that you can access. If your carrier allows, you can also use your SIM to pass information between phones and maintain some contact details.

How It Works

In TDMA, a narrow band 30 kHz wide and 6.7 milliseconds long is divided into three-time slots. Narrowband is a fancy name for the traditional radio channels we have (as opposed to broadband). So each conversation “broadcasts” for one-third of the 6.7 milliseconds.

This works because analog voice data is converted to digital data, then compressed to take up less transmission space. As a result, TDMA has three times more capacity than an analog system while using the same number of channels.

GSM Features

GSM networks have several useful features, which include:

• Data networking
• Applying encryption to secure phone conversations
• Call forwarding
• Multi-party conferencing
• Short Message Service (SMS) for paging and testing
• Call waiting
• Caller ID

GSM in Europe and Asia operates within the 890-960 MHz band, while in the USA it operates in the 1.9 GHz or 1900 MHz band. It is used within PCS-based and digital cellular systems, and it forms the basis for the popularized Integrated Digital Enhanced Network (iDEN) introduced by Motorola.

What Is CDMA?

CDMA is the other network system popular within the USA, and it works a little differently from the GSM network. It was developed during the Second World War by the Allied Forces, mostly to prevent Nazi forces from hampering communications by jamming radio signals. It is mostly found in Russia and the USA, but it is becoming popular in other countries.

What Does CDMA Mean?

CDMA stands for Code Division Multiple Access. CDMA gives its users complete access to the whole spectrum of bands, which means more users can connect at a given time. CDMA also works by encoding every user’s conversation through a pseudo-randomized digital sequence. As a result, only those participating in the call will receive the correct and complete data, offering better protection and privacy.

Instead of having SIM cards to identify users, CDMA network phones were built specifically to connect onto a specific carrier’s network. Therefore, buying a phone from one carrier limited you to the carrier and their bands. Should you need to change providers, you would have to change phones.

Because of technological advancements, some carriers can unlock phones allowing you to switch the phone to a different carrier. However, it is more common for CDMA carriers to use SIM cards, although now they carry LTE networks.

The Differences between GSM and CDMA

Both GSM and CDMA are multiple access standards, which means that multiple calls can be sent through one tower. The major difference between them relates to how your data is converted into radio waves for the phone to broadcast and receive. Apart from that, here are some practical CDMA vs GSM differences that affect you at the consumer level:

SIM Cards

As mentioned, before 4G LTE was invented, CDMA devices did not have a SIM card, while GSM devices came with SIM card slots. That is, CDMA was a phone/handset-based standards, where the phone number was linked to the handset/device. If you needed to upgrade your phone, you’d have to talk to your network carrier to deactivate the old device and activate your new device.

Conversely, for GSM devices, your phone number is linked to the SIM card, so popping the SIM card to a new device allows you to retain your identity. Although, some GSM devices may still be locked to network carriers, especially in the US.

Network Coverage

Network coverage doesn’t have anything to do with CDMA or GSM as separate standards. Rather, the infrastructure of the carrier determines whether or not you’ll have coverage. GSM networks are still more popular globally than CDMA networks. However, in the US, CDMA carriers have the broadest coverage and the largest number of active subscribers.

Roaming

At home, it really doesn’t matter which network you’re on as long as you have coverage. If you travel, though, you’ll be interested in what your carrier can do when you’re away from home. GSM has an edge over CDMA for roaming, because it is far more popular worldwide, and carriers make roaming deals to ensure you stay connected.

If you have a GSM phone, you can also pick up a local SIM where you are, assuming your carrier hasn’t locked the device to their network. You may not have full internet connectivity depending on device and network compatibility, however.

GSM and CDMA Carriers

If you’re a customer in the USA and you’re wondering which network carriers carry which kind of network, the answer is pretty much 50 percent for both sides.

When you’re thinking about a network carrier, think about how the carrier suits your needs, preferences, and budget. Consider their service quality, network infrastructure, features, phones, and services. Always check with your network before investing in a new phone, to ensure that it will work with your carrier.

It is possible for carriers to switch from GSM to CDMA and vice versa, but given that technology is wheezing past 4G and into 5G, many carriers don’t think it’s worth the trouble. This is why Verizon retired its 3G network and is now moving towards 4G and 5G. Many other carriers are likely to follow suit in the coming time.

Final Thoughts

For many carriers, going into CDMA or GSM was a matter of timing. Earlier carriers adopted GSM because it was the only available one at the time. When CDMA came into being, carriers that were opening shop jumped at the new thing that was better then. GSM soon caught up with the features of CDMA, which is why your choice isn’t so clear-cut one way or the other.

Before choosing or switching your phone or network carrier, take time to find out how they will suit your needs, not just what it means for your pocket. If you get the wrong device, you might have a hard time switching or changing carriers or plans once you’ve signed up.

Nowadays, most small business transactions and networking happen on the go. You don’t work the usual nine-to-five, so why buy a business line and all the equipment that goes with it? All you need is an open line of communication with your customers, and you already carry it in your pocket.

Your cell phone is the most accessible solution, and you can use your cell phone for business without customers even knowing that it was never originally a business line. Here are five tips for keeping it professional and building your reputation while using your cell phone for business.

1. Update Your Voicemail For Business Calls

What’s the difference between a personal vs. professional voicemail greeting? What should a business voicemail say?

With both types of voicemails, you must know your audience. The issue is that you have two different audiences, and your voice messages will differ accordingly. So, be tactful and friendly in voicemail greetings for work.

A personal voicemail greeting typically includes your name, represents your personality and may include a joke. A professional voicemail greeting contains your name and the business name, represents the brand and may include your company’s social media or alternative contact information. The most thoughtful professional voicemail tells callers that they will receive a return call, not that you are going to “try” to call back.

How can you record a voicemail that suits both your personal and business worlds? Remember, your voicemail serves as your first impression:

• Keep it short and to the point, allowing a pause before you begin recording.
• State your name and the name of your business, and provide a brief directory if relevant. Allow callers to press # to skip the greeting and leave a message.
• Skip the jokes.

Default voicemail greetings are not welcoming and are confusing for all callers. Think of your business voicemail greeting like a good elevator pitch, and practice before you record.

2. Always Answer Professionally

What kind of language and tone do you use when you talk to your mom vs. your best friend? How would you greet someone that follows up with you from a conference?

What do you say when you first pick up the phone personally vs. what do you say when answering a business phone call?

Much of communication remains unseen when on the phone, so your tone is even more important to building rapport. Different tones affect the mood of the listener and make a powerful impression.

However, your nonverbal language still affects how you communicate. Sit up straight. Make sure your voice is clear, and stay hydrated. Smile into the phone as you speak.

Always answer a phone call professionally, not casually. You don’t want to sound dry. The energy of your tone sets the energy for the call. So, be tactful, warm, and confident. Pace yourself as excitement and anxiety can make you speak a little too quickly.

The most professional answer is similar to recording a professional voicemail greeting in that you state your name and the name of your business: “Hi, this Joe, CEO of The Greatest Business Ever.”

Always assume it’s a business call. Answer consistently to build trust which in turn builds the reputation of your business.

3. Stick to Your Business Hours

Define your typical business day upfront. What are your normal business hours, and what are your non-business hours?

Consider how personal contact might affect your availability for business contact. This consideration also links to how you schedule your day. When are you available, and for what?

It’s important to schedule moments to invite positivity into your business day, whether that’s meeting with a mentor or going to the gym for 30 minutes midday. Don’t schedule the most stressful meetings back to back.

Relating to business phone calls, do you consider yourself available when in a noisy environment? Some professionals think it’s important to take client calls wherever they are, but the client, or even a relative, may not see it this way. Accepting calls at this time, for business and personal, can make the other party feel unimportant. Let calls in noisy environments go to voicemail.

4. Set Rules for Personal Calls

Set rules for personal contact, which means your business hours must be kept firmly in mind. Will you take personal calls at work?

If so, when? Will you accept return personal calls during your lunch or for a short period in the afternoon? Must personal calls and texts wait until after you close for the day? It’s very important to practice proper cell phone etiquette at work, even if you’re a solopreneur.

Set boundaries for personal calls, and clearly communicate your business hours. Communicate under what circumstances you will take calls and when you will return calls. Keep your promises to loved ones and clients. Setting boundaries will keep you focused and present for both.

Consider directing friends and family to connect with you via Facebook Messenger or WhatsApp. This will help keep the personal and professional separate.

Extend phone call etiquette into texting etiquette, and determine rules for yourself. Will you only text friends and family? Will you also text clients? It’s important to be mindful of whom you text, so you don’t get into any tricky or embarrassing scenarios.

5. Be Prepared to Handle Various Types of Calls

Consider sales and customer services departments and how prepared they are to handle all kinds of calls. How will you handle calls for quotes, demos or a followup? What if someone is interested in having you as a speaker? What if your mom calls and texts you that it’s an emergency?

Which procedures will you follow? If you don’t have a confident way of handling circumstances, it can lead to the perception that you are inexperienced in business due to your inconsistency. In matters concerning loved ones, it can look like you don’t care.

You are the best advocate and knowledge base for your business. The more you have ready to go, on the go — the more confident and informed you will feel and come across to others. So, know your mission, your products and your pitch. Where do your products ship from? How well do you know the industry? Have you read the latest research? Where do you see your business going in the next five years?

You’ll also answer customer service calls, so be prepared to address concerns with empathy and action. Customer service calls provide vital information for your business, especially when it comes to feedback and areas of improvement. So, don’t provide stop-gap solutions.

You won’t have all the answers, but be determined to find the answers and work through problems. Engage with your clients, and you will build loyal, powerful business relationships.

Yes, you can use your cell phone for business. You gain an office in your pocket when you use your cell phone for business, increasing your mobility and accessibility which makes a professional and positive impression.

However, you need to set a few ground rules and protocols. Make your first step updating your voicemail to a professional greeting that states your name and the name of your business. Set and stick to your business hours, and determine rules for personal calls so you can be available for both clients and loved ones.

By using your cell phone as a business phone, you get to take advantage of endless mobile tools to take your business to the next level. This allows you to build your reputation as a budding business who will fundamentally change the market for the better.

SIM cards help you to stay connected to your loved ones, and there are few things you can do on your phone without a SIM card. Therefore, understanding the SIM card meaning and what it can do will help you do more with your everyday devices and tools. Besides, you will understand your options when choosing the ideal card for your phone.

Regarding the SIM card definition, it’s a tiny plastic chip or circuit board that slots into your phone to give you a unique ID and connect your phone to the cellphone network. Without it, for example, you cannot make phone calls or send network-enabled messages.

So, what is a SIM card used for? Learn everything you need to know about SIM cards in the article below!

What Does a SIM Card Do?

As mentioned, the SIM is the card that connects your phone to your carrier’s network. It is through this card that your carrier identifies your phone within their network.

In simpler terms, it is like a memory chip which stores your unique cell phone identity. For example, the chip contains a unique seventeen-digit code which tells the carrier the country of origin, the carrier network (e.g. Verizon or AT&T), and your unique user ID. This is the information the carrier uses to attribute your cell phone usage for billing purposes.

You can transfer your SIM card from one device to another and still incur the same charge according to your usage because of the ID information. There are also certain features on your phone that will only work in the presence of a SIM card. For example, you cannot turn on mobile-enabled data without a SIM.

How does a SIM card work?

The most important piece of information your SIM card holds is the International Mobile Subscriber Identity (IMSI), which is the seventeen-digit code described above. This IMSI is validated by an authentication key which your carrier provides.

This is how the carrier authenticates your SIM and allows communication:

•  When you turn on your phone, the phone reads the IMSI and transmits it to your carrier, sort of like a request for access
• The carrier receives the IMSI and checks in its internal database for its authentication key
• The carrier network generates a random number, e.g. “U” and signs it using the authentication key to create a new number, e.g. “Q”. The network knows what number to expect if the SIM is legitimate
•  If legitimate, the network transmits “U” to the phone, which in turn forwards it to the SIM card
• The SIM signs it using its own authentication key to create a third new number e.g. “F”, which it relays back to the carrier network
• If the carrier’s number “U” matches the SIM-generated number “F”, the network declares the SIM legitimate and allows access for communication

You can change your phone without being refused access to your SIM card. In most countries, however, your SIM card and device is tied to the carrier network where it was bought. This means that your card won’t work in a device sold by a different carrier. However, your carrier can help you to “unlock” the device to allow you to use a SIM from another network.

Can a phone work without a SIM card?

The SIM card is the brain that runs your mobile phone, so there’s very little you can do without your SIM card in the phone. It is possible, for example after damaging your phone, to move your SIM to a similar device and immediately retrieve your data, contacts, and other data within minutes.

A phone without a SIM is nothing but an expensive iPod/camera/gaming device. You can still use Wi-Fi to access the internet, take pictures, listen to music, play games, and use the calculator. But you can’t make phone calls, send text messages, or use apps that require SIM access, like Uber.

What information is stored on a SIM card?

Apart from the identification and authentication details, your SIM card can store a small amount of information. It can hold up to 250 contacts, a few SMS messages, and some other details needed by your carrier. Most SIM cards can store 32-128KB of data, but they are almost never used now because of the massive internal storage capacity of today’s phones.

To transfer data in the SIM, you must move it from one phone to another, and then copy the details into the phone’s internal storage. However, this is almost no longer necessary thanks to backup apps and cloud storage.

SIM Card Sizes

There are different size SIM cards available in the market now. The first SIM card ever built in 1991 was the size of a credit card, but they have been reducing in size since then: today, the smallest SIM is called the embedded SIM, and it measures 6x5mm.

The mini SIM or standard SIM was used on older devices; today, devices mostly use micro and nano SIM cards. The size of the circuit board is the same; the only difference is in the size of plastic surrounding the board.

Do SIM cards fit all phones?

Most carriers will provide you with a 3 in 1 SIM card, which means the card comes precut into the mini, micro and nano SIM sizes. If your device has a nano slot but you need to change to a device with a mini or micro slot, you can use the provided SIM card adapter to ensure your circuit board sits at the right place in the SIM slot.

Below are the different sizes of SIM cards:

Standard SIM

The standard SIM card or mini SIM was introduced in 1996, and it was used for every mobile device. It measures 25mm by 15mm with a cut-off corner. It remained standard for over one decade before the introduction of the micro-SIM. The standard or mini-SIM is still provided by carrier networks so that they are compatible with older phone models (usually non-smartphones that are more common in developing countries).

Micro SIM

The micro-SIM was first introduced in 2003 for devices with SIM slots that were too small for mini-SIMs. Micro SIM dimensions are 15 by 12 mm, with a cutoff corner.

However, the uptake of the micro-SIM was very slow; it wasn’t until 2010 that Apple first adopted the micro-SIM for their iPhone 4. Other manufacturers followed suit. Your SIM card still comes with a micro SIM adaptor for your nano SIM, should you need to switch to a device with a micro SIM.

Nano SIM

Finally, the nano SIM card was introduced shortly after Apple took up the micro SIM. By the time iPhone 5 hit the shelves, Apple had switched to the even-smaller nano-SIM. Switching to the iPhone 5 was a little difficult for users, as they had to get a new SIM or use an adapter. Nano SIM dimensions are 12.3 by 8.8 mm.

However, phones made after 2014 now support micro SIM vs nano SIM technology. Those with two SIM slots usually have one of each.

Final Thoughts

Now you understand everything there is to know about SIM cards and how they work. As a final note, it’s worth mentioning that you should do your research between network carriers carefully before settling on a carrier. Otherwise, moving to a different carrier once you’ve gotten your device and cell-phone plan could be very difficult.

To ensure that you’re not using too much data, you must regularly check your data usage on your phone and compare it to your bill to stay within budget. You can also set limits to your data usage to help keep you on track. However, depending on the apps you use and your business needs, you may need the amounts of data you’re currently using.

What Uses Data on a Cell Phone?

Your cell phone’s mobile data is the amount of data used in one billing cycle, typically a month. Cellular data is used any time you are using your phone’s internet connection to complete a task.

What counts as data usage, and what uses data on your phone? Here are a few common ways that data is used on a smartphone:

• Searching the internet
• Downloading or running apps
• Posting on social media accounts
• Playing games
• Streaming video
• Streaming audio
• iMessaging (iPhones only)

Apps that use data while doing any of these activities can make your bill run high. In terms of your business cell phone plan, the data you use while connected to WiFi doesn’t count against your data plan’s usage.

What Is Background Data?

What the difference between foreground and background data? How do you turn off background data?

When an app isn’t being actively used by you, the data consumed is known as background data because it’s happening behind the scenes, passively.

So, what is foreground data? Well, if you have an app displayed on your screen and you are actively engaging with it, then you are using foreground data. Once the app is closed, data that it continues to consume is background data.

What does “restrict background data” mean? You’ve probably seen these terms referenced online and on your phone. However, it’s important that you know that background data consumption is intrinsic if you rely heavily on notifications.

If you restrict background data, then apps won’t be allowed to send you notifications unless you’re actively using the app. The app itself doesn’t handle background data; the operating system does.

If you use many apps or widgets, then you need background data. If you don’t, then it may be best to restrict or turn off background data. Also known as “low data mode” in iPhones, automatic updates and background tasks are paused when you restrict background data.

How to Check Data Usage

You may be wondering, “What is using my data? Which apps are using my data?” The best way to check data usage is to look at your cell phone’s settings. You can then see how much data you have used overall and how much data each of your apps are using. You can manually switch off the ones you don’t often use.

On an Android, this is done by going to Settings -> Connections -> Data Usage.

On an iPhone, this is done by going to Settings -> Cellular -> Current Period Section.

How to Use Less Data

Reduce data usage to optimize both your phone and day, while saving money over time. Different apps take up more data than others. So, how do you turn on your data saver?

iPhone (iOS)

Set the data limit on iPhone (iOS) and turn off “push notifications” for social media, emails and GPS apps. Go to Settings > Notifications > Select the app, for example, Facebook > Switch Allow Notifications off.

Turn off autoplay for video. Change the settings in apps like Instagram and Facebook so videos don’t automatically play.

Restrict mobile data. Make sure certain apps run only over Wi-Fi. Go to Settings > Mobile > Scroll down to Mobile Data > Switch off mobile data for apps that you don’t want to run over the cellular network.

Please note that pressing the Home button to exit apps does not fully stop the app from using data in the background.

Android

Turn off “push notifications” for social media, emails and GPS apps. Go to Settings > Notifications > Switch off notifications for selected apps.

Turn off autoplay for video. Alter your settings in apps like Instagram and Facebook so videos do not automatically play.

Restrict cellular data for certain apps, as needed. You can restrict certain apps from using background data. Go to Settings > Apps > Select an app > Switch off “Allow background data usage.”

Turn on Data Saver mode to conserve mobile data. If you don’t have unlimited, turn on Data Saver. Go to Settings > Connections > Data Usage > Turn on Data Saver mode or restrict data usage for certain apps.

Only use Viber or WhatsApp when you’re connected to WiFi if you want to avoid a data drain. So, when traveling abroad for business, double-check that your data roaming is off.

Background data really drains the megabytes. Fortunately, you can reduce how much data you use by taking actions like turning on Data Saver and manually turning off notifications for certain apps.

For entrepreneurs and professionals on the go, you know that apps are intrinsic to staying relevant and connected. Who wants to miss an opportunity?

Not a Teltik business cell phone plan customer, and they won’t because they don’t have to worry about wasting data while on an affordable and unlimited plan.

However, most businesses have encountered the dilemma of picking the best mobile OS for business. Choosing between iOS vs. Android for business means looking at the hardware, cost, security, and software features. Ideally, you want an option that makes your team productive and efficient.

We’ll guide you on making the decision between using an iPhone for business or an Android for business.

Which Is Easier To Use: iPhone Or Android?

When iPhone devices first appeared, Nokia Symbian and Windows mobile phones were the competition. However, iPhone was quick to beat them because it was easy to use. So, the question is, is iPhone easier to use than Android, or is Android easier to use than iPhone?

Today, both iPhone and Android devices are easy to use. Android, however, gives you more control than iOS. Of course, there’s a learning curve if you have never used any of the OSes. For business use, the choice of an OS largely depends on user preferences, and employees tend to go for iPhones. So in a way, both of the phones are easier to use. When you look at the home-screen setup and appearance, Android feels somewhat a great option, and it offers more features for power users. iPhone, on the other hand, is more streamlined, and many people are familiar with it.

Well, are iPhones easy to use? iPhones are user-friendly as they allow you to do everything quickly. Also, their interface is considered the best-looking when compared to Android. However, the iPhone is limited when it comes to customization.

Android vs. iOS Security

Your smartphones should just be as secure as your business computers. Both operating systems have had high-profile security issues over the years. Nevertheless, Apple seems to do more to keep their devices secure and your data private than Google.

So, is iPhone more secure than Android? You could say that, but your device’s security also depends on how you or your employees use the smartphone. For example, using public internet connections pose a risk of getting hacked or facing malicious attacks.

Unlike Apple, Google is more lax about what applications get approved to its app store. At one time, the tech giant reported that 0.16 percent of all the apps had malware. Even so, the Google Play Store is still a secure way to get apps.

Is iPhone safer than Android? iOS boasts a better security reputation than Android, but it’s far from being unhackable. One great thing about the OS is good legacy support. Older versions of the iPhone continue to get firmware and security updates to ensure they’re safe.

Regarding Android, it’s widely used by different phone manufacturers. This widescale use might be problematic since some flagship models ship with different versions of Android. It takes time for manufacturers to update some of the versions, and this might present security holes for malicious attacks. On a positive note, the open-source nature of Android means security risks are discovered and fixed quickly.

As noted before, your device’s security also depends on how you use it. Monitoring your business network systems and implementing a solid corporate-owned device policy should help boost your security.

iOS vs. Android For Productivity

When looking at work experience and productivity, Android seems to have the edge over iOS. But then again, it depends on what you’re using the device for.

Both OSes come with default email apps that are easy to use and allow you to connect multiple accounts. They also allow you to download third-party email apps. However, Gmail, which is Android’s default email app, is much better than iOS’ Mail. Plus, it’s the most popular email system in the world.

On storage, Android productivity seems to win again. Unlike the iPhone, you can extend the storage capacity of your Android device using a microSD card. Android also offers Google Drive to store everything from photos to work files. iPhone also has the iCloud service for storage, but the free tier only offers 5GB, compared to Android’s 15GB.

Regarding iPhone productivity, you can quickly get Microsoft office on iPhone as it’s free to download on the App Store. You can create, view, send, and edit Office files using the app. This also applies to Google Docs on an iPhone. You can use the Google Docs app to share files and collaborate with your team.

Google Docs on Android is also easily accessible by downloading the app from the app store. It offers all of the features you need to create and edit your files. Using Microsoft Office on Android is just as simple as iOS, as you download the app from the Play Store.

Both OSes offer different features and apps for boosting productivity. For example, Google Voice (available on Android and iOS) converts your voicemails into texts or emails for you to read later. You can also turn off notifications to avoid distractions or use voice assistants to make calls or access information on the go. They also both have split screen capability, but it’s easier to do on most Androids.

iOS vs. Android Technology

Regarding mobile technology, each of the OSes excels in some aspects. For example, iPhone has continually outperformed Android in software technology. iOS is a unique system that is only used on Apple devices and systems. Apple also beats Android in releasing timely updates for its software.

Older supported iOS devices continue to get functional improvements to offer additional software features. On the other hand, Android devices that are more than a few years old generally don’t get such software improvements, and one might need to get a new phone to get the updates and features they want.

The topic of Android apps vs. iOS apps is also an area worth looking at when comparing the two OSes. iPhone has better app selection than Android for a good reason. Most app developers make more money with iPhone apps, so you get more apps and premium app features with iOS than Android.

But some apps are specific to each of the OS. For example, Apple’s iTunes is only available on iPhones. But this difference is insignificant as you can get alternatives for your Android device.

Regarding iPhone vs. Android hardware, Android has a vast hardware diversity. Apart from Apple, nearly all mobile phone manufacturers use Android on their devices. This means customers have access to a variety of phone options with many different sizes and shapes. You can choose a phone with a high quality camera, a built in keyboard, an included stylus, or many other features.

With Android, you can get a big-screen phablet like Google Pixel 4 XL, the latest and greatest model, such as Samsung Galaxy Note 10, or a small cheap option like a Moto E6. Android’s hardware compatibility, however, doesn’t keep up with iOS’. iPhone’s Continuity feature lets you connect your device to an iPad or Mac. This only works across Apple devices, however. One issue with iPhones is the removal of the headphone jack, which limits you to Bluetooth earphones.

When considering building an app for your business, Android vs. iOS development might present a dilemma. You want to look at your target market, cost of development, time, and difficulty. Android apps are developed in Java, while iPhone Apps are developed in Apple’s Objective-C language, which is simple to learn if you understand C and C++ languages.

Android app development might be complicated due to the variety of devices that it supports. Some devices might have different needs and features. It’s also time-consuming. However, it offers better testing tools than iOS development. Android OS is also more versatile, and it allows multitasking.

Conclusion

When looking at the Apple vs. Google ecosystem, it’s vital to understand each OS’s features, benefits, and cons. Picking the right operating system for your business can boost productivity and improve efficiency. But then again, your employee’s preferences also play a role in decision making.

Regarding iPhone vs. Android prices, Android offers a wide range of phones, ranging from dirt cheap devices to high-end options. iPhones don’t have as many options, and they tend to cost more, so it’s a matter of planning your budget and determining the number of devices you want. You’ll also need to consider if you’ll be replacing the devices sooner.

Whichever phone OS you decide to go with, there’s one more thing you’ll need to make it complete – a phone plan designed for businesses. So why not choose Teltik? It’s compatible with pretty much every Android and iOS phone, and it has many features specific for businesses. Go and give us a try today!

If you spend a significant part of your life traveling long distances, knowing what data roaming is and how your carrier treats it could be a lifesaver. It will allow you to use your phone as you travel without being worried about huge bills.

Learn below what data roaming is and how it affects various aspects of your cell phone plan.

What Does Roaming Mean?

Data roaming is what happens when your phone goes somewhere where your primary network has little or no coverage. Usually, cell phone carriers have partnerships with each other to help their customers still get service without having to switch SIM cards.

As a result, your phone will seamlessly jump onto the carrier with a stronger network, but you still use your phone as if you’re on your regular network. Depending on the carrier, you may be charged extra for the convenience of not having to change SIM cards. For example, Teltik does not charge extra for domestic roaming, even though some carriers do (more on this later).

What Does Data Roaming Do?

Suppose you are a US citizen who uses a cellphone service provider that gives you 4G data and a phone signal. Summer has reached its peak, and it seems like a good time to travel to Europe for a vacation. You go to Spain to sit by the beach and you’d still like to stream your beloved podcasts and YouTube videos as you sip cocktails and get tanned.

There’s just one problem: Your carrier doesn’t have network coverage in Spain. So now you’re in Spain, and you need a new SIM card from the local provider, Movil Espana.

It’s expensive and tedious to get a SIM card, register for a plan, set your APN and buy a package, all for a week-long trip. And that’s assuming your phone isn’t locked to only use your carriers signals.

Your carrier has foreseen such scenarios, so they have made arrangements with different carriers in different countries, including Movil Espana in Spain. In return, when Movil Espana customers come to America, your carrier will give them a phone signal and will support them on their local plans.

What Does It Mean When Your Phone Is Roaming?

Because of this arrangement, once you land in Madrid, your phone automatically picks up Movil Espana. Now you can receive service as though you’re still in America, but most likely for a fee. You may pay a little more for the convenience of not having to change SIMs or registering a new line.

Depending on your settings, your phone won’t automatically pick up Movil Espana network when you land; you must turn it on. Once you manually turn on Data Roaming in Settings, you can enjoy 4G coverage and use your phone as you normally would. Your screen will show the local network, but your plan will be the same as the one you were using back home.

What Is Domestic Roaming?

Even within America, cell phone carriers have roaming agreements with one another so they can cover each other when customers go places that have little or no coverage. The jumping from one network to another locally is often seamless so you won’t even notice that it’s happening. You just keep texting, calling, and accessing the internet as usual.

If your cell carrier doesn’t have a roaming arrangement with the carrier whose signal is strong, you may go without coverage. However, most service providers have existing roaming arrangements with each other.

Confirm with your carrier if you have any questions about domestic roaming. You should also find out if there are charges to domestic roaming. If so, you need to manually turn off domestic roaming in your settings to prevent huge cell phone bills.

What Is International Data Roaming?

International data roaming is what happens in the above example. In many countries, American cell carriers have made roaming arrangements with local providers to give uninterrupted cell service. However, you may pay extra to use the privilege. The cost varies according to the home and foreign network involved.

Check with your provider to see what their international roaming charges are. If you aren’t able to switch to a cheaper carrier in time for your trip, buying a local carrier’s SIM may be more cost-effective, especially if you will be away for a long time.

What Is LTE Roaming?

LTE roaming simply means you can use LTE services by another carrier, not your regular LTE network provider.

Roaming Charges

If you travel outside of the coverage area of your regular provider, whether domestically or abroad, you won’t access services. That is, unless you activate data roaming — and this may come with data roaming charges, depending on your carrier.

What are Roaming Charges?

Teltik gives free data roaming on domestic networks, for example, but very few other networks allow free domestic roaming. Before a long-distance trip or a trip abroad, find out whether your provider has extra charges for data roaming.

Sometimes, your phone may attempt to use roaming services even if your carrier is in the area. This happens if the other carrier’s network is stronger than your primary network. But you can limit this when you disable or enable data roaming.

How do I know when to turn data Roaming On or Off?

To know whether to use data roaming or not depends on your destination and your need for the service. As a general guideline, it is better to keep the data roaming setting off and then turn it on manually when you need to use your cell phone.

How to Turn Off Roaming

On Samsung Galaxy and similar Android-powered devices, navigate to your Main Menu (swipe down on the home screen) and choose Settings>>Wireless and Network>>Mobile Networks>>Data Roaming. If the box has a check or slider for on or off, uncheck or slide it off.

On an iPhone, choose the Settings app from the home screen, then select General>>Network>>Data Roaming. Turn the slider off and do the same for Cellular Data.

Mobile Data vs. Data Roaming

Many people ask, “What is the difference between data roaming and mobile data?” The phrases ‘mobile data’ and ‘cellular data’ can be used interchangeably. Phone data/mobile data is simply the ability to use uninterrupted mobile internet services given by your primary provider.

Data roaming is the same, except you use a carrier other than your primary signal provider. So on data roaming, you access the internet with another network’s coverage.

The data speed or roaming speed for both options depends on how strong the signal is, and whether the provider has 4G or 3G coverage. The latter will have slower internet speeds, whether it’s from your primary provider or a roaming network provider.

Final Thoughts

Now that you know all the basics of data roaming, cellular data, and their roaming charges, you may wonder what the best roaming service provider for you would be. Depending on the amount of data, text, and talk you need, as well as your home address and where you are traveling to, different carriers have different plans.

Be sure to research extensively before your trip to avoid any nasty surprises when you come back home, and enjoy your trip!

For many people, the knowledge of IoT extends only as far as using IoT devices; they’re not motivated to delve into what it is and what it can do. Before thinking about IoT specifically, consider what you’re using to read this article – your tablet, smartphone, or PC (laptop/desktop). Whatever it is, it’s probably a device with an internet connection.

The Internet was a real game-changer; it has put options in our hands that we could only ever imagine. If you had a cellphone before they were smart, you know that you could only call and text. Today, you can make purchases, watch movies, read books and articles, and more — all thanks to internet connectivity.

In this article, we delve into IoT technology and how it has changed the world we live in today. Read on to learn more:

What Is IoT?

If you have ever tried to Google the definition of IoT technology, you were probably bombarded with an unnecessarily technical definition. It need not be so complex, however.

What Does IoT Stand For?

IoT stands for “Internet of Things”, and it mainly refers to devices that ordinarily would not have an internet connection, but do. For example, smartphones or PCs are not part of IoT even though they can access the internet. But a lightbulb you can turn on with your phone is IoT.

What Does the Internet of Things Mean?

The Internet of Things is not complex to understand: it simply means making all interrelated devices able to connect to the internet or communicate without requiring human involvement. IoT has a world of possibilities, many of which we have already seen and use, but many others that we can only imagine.

Benefits of IoT

When thinking about the benefits or uses of IoT, we begin by thinking about the benefits of having a connection to the internet. Devices that are connected to the internet can send or receive information very easily. It is this ability to communicate through the internet that distinguishes “smart” devices from non-smart devices.

For example, because of the internet, you can listen to any song you want right now, even if you don’t have it on your phone. Your phone sends information (to ask for the song) and receives information (the song being streamed).

A device doesn’t have to have a super-computer or super-storage to be considered smart; it just needs to be connected. There are three categories of IoT devices:

• Those that collect and then send information – think sensors for motion, temperature, moisture, light, air quality, etc. They collect information around them and transmit to humans or other devices to help make more intelligent decisions or drive other actions.
• Those that receive and then act on information – think printers that receive information from your PC and respond by printing, or your key fob that sends a signal to your car which then opens.
• Those that do both – this is where the real IoT potential lies. For example, there are soil sensors to tell the farmer when to water his crops to conserve water. Instead, if the sensors were connected to an irrigation system, the farmer wouldn’t even need to be notified. You can even go further and connect the irrigation system to the weather forecast so that it doesn’t water crops when rain is anticipated.

The real power of IoT doesn’t end with receiving and sending information or even acting on said information. For example, with our example above, soil sensors can be programmed to collect lots of other information.

When hundreds of soil sensors in different places are programmed to collect all kinds of data, powerful algorithms can make sense of all the information. In turn, we can learn which crops grow best where and when, among other insights.

The IIOT

The IIoT stands for the Industrial IoT or Industrial Internet of Things. These are the countless industrial devices that are fitted with sensors, connect to wireless networks, and collect and transmit different kinds of data.

Technology has created thousands of low-cost sensors that can be fitted on the smallest devices to give them digital intelligence. These sensors enable monitoring/tracking, communication, and data sharing. This data can be analyzed and used to improve efficiency and productivity.

The IIoT is already making billions: according to IDC, IIoT spending will account for $329 billion for transport, manufacturing, and utility companies in 2019. Consumer spending on IoT is also significant – about $108 billion, primarily on personal wellness, connected vehicle infotainment, and smart home devices.

Benefits of IIoT Solutions

The IIoT has the potential to facilitate better and more intelligent data-backed decision-making. Many businesses are working on digitally transformative projects, and they can benefit from the additional data provided by IIoT. They get highly detailed, real-time data to provide insights into their business processes, and to identify new business opportunities.

Many industries are adopting IIoT, including manufacturing, utilities, transport, and retail industries.

IoT in manufacturing provides insights into the production lines’ operations. Companies can be notified when different machines need servicing or are performing below par to prevent unexpected downtimes.

Utilities can use IIoT to make remote installations self-monitoring so that staff doesn’t have to be sent for troubleshooting. Retailers can use IIoT to identify opportunities for expansion or identify bottlenecks or inefficiencies in the supply chain. Transport and logistics companies can use IIoT to understand the performance of their fleets and improve communications and tracking.

IoT in Business

The Internet of Things has found numerous applications in business and related services. Some of the applications include:

• IoT security – IoT sensors, IoT monitoring, and IoT trackers can help beef up security. Attacks or breaches can be identified and dealt with promptly
• IoT asset management – In this case, you can use IoT to keep track of your assets
• IoT in logistics – with all the variables, IoT monitoring can help smooth out logistical flows, facilitate planning and delivery, and notify customers as needed
• Work efficiency – just like IIoT, IoT in business can help identify inefficiencies and gaps, opportunities, and threats, and hence increase productivity. Maintenance downtimes will decrease because of real-time information on the performance of various machines
• Customer experience/service – having real-time information makes customer service flow smoothly and easily, increasing customer satisfaction with help received
• Data generation – IoT is putting more data in businesses, which will add great value to business decision making. Cisco estimates that IoT data will account for 500 zettabytes (1021 bytes) of data by the end of 2019

Irrespective of the size and industry of businesses, IoT will become a crucial part of business operations within the next few years. IoT and IIoT have the potential to revolutionize business operations, causing unprecedented growth and expansion for businesses that apply it correctly.

Examples of IoT Applications

The vast majority of IoT applications include local sensors that transmit information for various purposes. These sensors may also receive information to drive certain actions according to predetermined workflows.

Some examples of IoT applications include:

• Smart locks
• Cellular dash cams
• LTE dash cams
• Arlo Go security cameras
• Cellular security cameras
• LTE security cameras
• Arlo Cellular
• mPOS
• Data loggers
• RFID IoT
• GPS trackers

• Fleet management
• Fleet telematics
• Digital signage
• Cellular failover
• Routers with cellular failover
• LTE failover
• Failover routers
• Smart refrigerators
• And other smart appliances,

among others.

Final Thoughts

IoT is slowly growing to become something even more impressive: the internet of everything. Pretty soon, you won’t even remember what life was like when you had to get up to turn on a light switch in your house. You’ll be able to monitor your workplace from home or from halfway around the world, thanks to technology.

If you’re thinking about implementing IoT for any purpose, Teltik offers IoT plans with their phone plans. Choose your best plan today.

Most smartphones have this feature in their settings, and all you need is to set it up. Alternatively, there are apps, such as TP-Link Tether (iPhone/Android), that can help you set up tethering.

This article will tell you everything you need to know about tethering and cell phone plans. Read on!

What is Phone Tethering?

Tethering is a general term that means using your mobile phone or another mobile device with a connection to the Internet like a modem. This means that the device facilitates mobile connection for other devices, e.g. Wi-Fi only devices or laptops.

What Does Tethering Mean On a Phone?

You can tether your phone in one of three ways: USB tethering, Bluetooth tethering, and Wi-Fi tethering. In the first two types, you can only connect one other device, but wireless tethering allows as many as eight or more devices to use the same connection.

Some Wi-Fi-only devices that you can connect with include Kindles, Smart TVs, Wi-Fi-only tablets, etc. Data tethering allows you to use the same data plan on multiple devices, which lowers your data expenses.

Benefits of Tethering

Tethering offers internet access to those devices that don’t have an inbuilt 3G/4G mobile data access. If I don’t have any other means of internet access, such as a Wi-Fi hotspot in a restaurant or office, I can simply tether my phone and get the access I need.

Tethering can work anywhere your mobile data service provider has a connection. If you’re in the middle of nowhere and you need a map or internet for other reasons, simply tether the device to your smartphone.

If you have an active mobile data plan and your provider doesn’t restrict tethering, you can save money because you don’t have to pay separately. Simply tether phone to laptop and enjoy internet within the limits of your data plan. You don’t have to worry about buying a modem and paying for another plan for your laptop.

Data tethering also provides greater security when browsing, especially compared with a public/open Wi-Fi hotspot, for example. Your data is sent directly through your phone, and it becomes more difficult for a hacker to gain unauthorized access.

Additionally, if you tether your phone to a laptop via USB you have the added advantage of your battery being charged as you access the internet. You can also turn off Wi-Fi on the laptop if you need to conserve battery power since you have the phone as a modem.

Tethering versus Hotspot: USB vs Bluetooth vs Wi-Fi Tethering

There are three ways to share a smartphone’s internet connection: Wi-Fi, USB, and Bluetooth.

Of these, Bluetooth is the least advisable because it is slower and allows you to share with a single device only. Bluetooth tethering uses less battery power and offers better security than Wi-Fi hotspots.

However, it uses more power than USB tethering and offers a slower connection than the other two options. Configurations for Bluetooth and Wi-Fi are also fairly technical.

USB tethering is faster, and it allows your laptop to charge your phone so you don’t lose battery power. USB tethering does require you to have your USB cable at all times, and there may be special configurations to set up both the phone and the other device for tethering.

Wi-Fi hotspots are also fast, and they support sharing the same network with multiple devices. Most smartphones allow eight connections, but there are those that allow more.

Wi-Fi tethering has another advantage: today’s smartphones are capable of producing signal strengths that are on par with modern wireless routers. Whereas in the past, using a hotspot meant getting by with slower connections, today you don’t have to incur additional costs or walk around with many devices.

A downside is that you need a wall charger or portable battery bank because Wi-Fi hotspots are real power guzzlers. However, with Wi-Fi, your phone can be accessed by any hacker within your range. You must take the same security measures with your phone as with wireless routers at home or at work.

Is Tethering Better than Hotspot?

Whether or not tethering is better than Wi-Fi hotspots depends on your needs for the internet connection. For example, if you need a connection on multiple devices, the hotspot is superior to USB tethering in that case. But if you need to conserve battery power, USB tethering becomes superior.

Tethering is better if you need to be online for a longer time because it conserves battery power. It provides way better security than a public Wi-Fi hotspot, but slightly better security than a private Wi-Fi hotspot. Another advantage is that you can reverse-tether so that you use your laptop’s internet connection for your smartphone.

When comparing mobile hotspot vs tethering speed, the real determining factor of speeds is the connection of the mobile service. For example, a 3G SIM or network will offer slower speeds than sharing using Wi-Fi or USB tethering.

That said, USB connections often field faster signals than wireless connections, which is why, for instance, you’ll wire your smart TV to the router instead of just relying on the wireless Wi-Fi.

If you have a SIM and network with 4G capability, both Wi-Fi and USB tethering can access faster speeds than the regular mobile internet connection. This is because the phone is likely to have the latest Wi-Fi chipsets if the smartphone supports 4G.

Tethering Charges: How Providers Treat Tethering vs. Hotspots

Is tethering free, then? It actually depends on the mobile plans you’re using. With Teltik mobile plans, you can tether for free without any restrictions whatsoever. When you’re working outside, you can easily create a mobile hotspot and get your work done.

For example, you can tether a laptop to a phone using a USB cable or wireless connection such as Bluetooth. If you tether using a wireless setup, it might look like a Wi-Fi mobile hotspot, but the major difference is in the telecom provider’s models.

How Much Does Personal Hotspot Cost?

Most telecom providers have the mobile hotspot that consists of a device or adapter that allows computer users to connect to the internet from wherever they are.

They are advertised as an alternative to connections to LANs (local area networks) or public wireless networks, but there are personal hotspot charges to be incurred. They can be used to connect all devices with internet access, but they’re commonly used for laptops.

The majority of telecom operators sell the adapter or hotbox at a fixed price and give the mobile hotspot service at a monthly fee. This means the cost of using phone as hotspot has additional upfront costs and separate monthly charges.

With tethering, the model just includes using connectors to hook up a current wireless device to your laptop without incurring monthly charges. Many providers restrict the tethering option because the former option allows them to make more profits. Teltik is one of only a handful of providers that allows its customers to use tethering.

One might argue that mobile plan providers should not restrict tethering because you still have the same data limit. So it shouldn’t matter how you use that data, right? Well, that’s the rationale that Teltik uses to allow unrestricted tethering, compared with other carriers who add an extra $20-$50 with their tethering plans.

Final Thoughts

Be sure to check with your carrier regarding their tethering policies before you sign up for a long-term contract. Some allow tethering with a supplemental plan while others don’t allow it at all. If you have already signed up, you have no choice but to wait until your contract term lapses.

Teltik provides business cell phone plans with unrestricted tethering. Plans begin from as little as $20 per month, depending on your needs.
