Why Choose A Data Only SIM And How Can You Benefit From It?


Internet, today, has become the foremost priority of people all over the globe. With the advent of technology and internet-reliant software coming to the market almost daily, internet usage is increasing daily. Since smartphones are the prominent connectivity mode in today’s era, it shifted the momentum from normal SIM cards to data-only SIM.

This article will draw down the benefits of choosing a data-only SIM card over a conventional SIM and where they can be used other than your smartphones.

Data Only SIM: A Brief Explanation

A conventional mobile SIM card lets users make phone calls, send text messages, and use mobile data for internet connectivity. Whereas the data-only SIM card provides only the internet data. It means that with a data-only SIM, you cannot make regular phone calls and messages on any phone number. Still, you can use internet-operated messaging services like FaceTime, WhatsApp, Facebook Messenger, Skype, Google Duo, etc., to call and text anywhere in the world.

Things to Look at Before Buying a Data-Only SIM

Since the standard calling and texting is out of the question, your primary concern before buying a data-only SIM card should be the contract length, data allowance, and freebies to get more value against the money you spend. Let’s break these terms further.

1. Internet Data Allowance

This should be your priority before planning to buy a data-only SIM card. Most people are not sure about the amount of data they need. Therefore, they usually consume a fair bit of internet data without even knowing while downloading games and streaming their favorite shows.

If you have second thoughts about how much internet data you need, it is wise to initially sign up for a monthly plan and see how things go. This way, you can avoid paying a hefty sum for a one-year contract and regretting it afterward.

2. Contract Length

The second important thing to look for is contract length. Usually, the carrier operators require you to sign a yearly contract. But, if you know you want a data-only SIM for just a few months, there’s no need to sign a 12-month contract. Instead, opt for a one-month plan. This way, you won’t need to bear any extra charges.

On the other hand, if you’re sure about needing the SIM for a longer period, you can go for a twelve-month contract. By going for a one-year contract, you’ll probably be saving a few pounds as compared to the monthly plan.

3. G Connectivity and Discounts

As 5G has successfully been rolled out in various countries, it’s important to know whether your data-only SIM supports it. Some network providers offer 5G connectivity without additional charges, so opting for such networks is better. However, you must know whether your device is 5G compatible.

In addition to 5G connectivity, network providers offer special discounts and freebies to new customers. For example, O2 allows free membership to its customer reward scheme for every new customer who opts for O2’s data-only plans.


It is useful not only for your smartphone, but you can also use it for a couple of other things, such as in-car Wi-Fi and turning your smartphone into portable Wi-Fi.

1. For In-Car Wi-Fi

Have you ever seen a little SIM card slot beneath your car’s display screen? Well, that’s where a data-only SIM comes into use. Adding a data-only SIM to your car lets, you stay connected to the internet even while driving. Such as:

  • Getting live traffic updates on your navigation system.
  • Use YouTube or Spotify to stream your favorite music.
  • Receiving internet calls through your car speakers instead of your smartphone.
  • Use your vehicle’s system as a portable Wi-Fi hotspot for others to use their devices.
  • Stream your kids’ favorite shows on the backseat screens to keep them entertained during the journey.
  • Getting real-time directions from Google Maps.

2. For Turning Your Smartphone into Portable Wi-Fi

Another benefit of a data-only SIM is that it can be used to turn a smartphone into a portable Wi-Fi hotspot. When a smartphone operates as a modem, it allows other devices to connect to the internet, such as mobile devices, PCs, tablets, and gaming systems.

Portable hotspots connect to the internet via the mobile network, allowing you to go online even if there is no other internet source available. This can also be useful if you’re taking your work to your favorite local café that doesn’t have a public Wi-Fi network or if you’re traveling somewhere and won’t be able to get internet access for a while.

3. For Your Tablet

If you’re thinking of buying a Tablet, iPad, or Galaxy Tab for yourself or your kids and want to use it anywhere else than home, you’ll probably need a data-only SIM. Like your smartphone, the data-only SIM will connect your tablet to the internet and allow you to surf the internet anywhere you want.

One thing to remember before getting a tablet is that not all of them are SIM-enabled. Therefore, be sure to buy one that has a SIM slot. A tablet that does not have a SIM option should have ‘Wi-Fi only’ written on its box. So, be sure to check it before buying.

Data Only SIM vs. Normal SIM: Which to Choose?

With the widespread availability of web-based texting and calling apps that most of us use today, it is easy to satisfy your internet cravings with a data-only SIM. Especially if you’re living abroad, and your primary usage revolves around Facebook Messenger, FaceTime, WhatsApp, Telegram, or Skype to communicate with your loved ones back home, you do not require to spend money for international minutes and texts.

However, the fact that how much data you consume will be the ultimate decider of whether or not you’re really going to save any money. It is also worth mentioning that not all data SIMs offer free calls over the internet. Therefore, it is better to do some research before choosing a plan with any network provider.

Conversely, a regular SIM card would be a wise choice if you think you make lots of regular calls and messages. You’ll find several cheap options in the market, offering a fair deal with texts, calling minutes, and internet data.

For example, Talk Home offers free SIM card and an option of free delivery to your doorstep. Secondly, opting for Talk Home plans does not require signing contracts. Here’s a sneak peek to Talk Home’s cheap monthly sim only plans.


What Is The Difference Between A Normal Sim And A Data Sim Card?

The main difference between a normal SIM card and a data SIM card is the type of services that they provide. A normal SIM card, also known as a voice and data SIM card, includes voice call and text messaging capabilities and access to mobile data services.

On the other hand, a data SIM card only provides access to mobile data services and does not include voice call or text messaging capabilities.

Additionally, normal SIM cards are typically used in smartphones, while data SIM cards are typically used in devices such as tablets, laptops, and portable Wi-Fi hotspots.

Overall, the key difference between normal and data SIM cards is the type of services that they provide and the types of devices they are typically used in.

Can I Use A Data-Only Sim In A Smartphone?

Yes, you can use a data-only SIM card in your smartphone, but you will not be able to make or receive voice calls or send and receive text messages. You will only be able to access mobile data services, such as internet browsing and email.

Data-only SIM cards are typically used on tablets, laptops, and portable Wi-Fi hotspots. Still, they can also be used in smartphones if you only need access to mobile data services and do not require voice call or text messaging capabilities.

Which Devices Are Compatible With A Data-only Sim Other Than Smartphones?

Such SIM can be used in these devices other than smartphones.

  • iPad, Samsung Galaxy Tab, or tablets of any other famous brand
  • Laptops
  • Mi-Fi and Dongles
  • Modern cars
  • Any other device having a SIM slot

How Much Internet Data Does An Average Person Consume?

In the United Kingdom, an average person consumes around 3GB of internet data per month, according to a study by Ofcom – the UK’s communications regulator. However, if we talk specifically about the data-only SIM plans, the data consumption varies depending on the internet usage.

If you are sure your internet consumption is high, we suggest you go for a plan that offers 10GB of internet data or above per month.

Can I Use Data SIM Abroad?

Yes! You can use the SIM card abroad, but your data plan must include international roaming. Check with your mobile provider to see if they offer international roaming options for their data plans. Data-only SIM cards abroad can be expensive due to international roaming charges, which can quickly accumulate. When traveling abroad with a data-only SIM card, you should carefully consider the costs and availability of international roaming.
