The best prepaid data only SIM card in May

When using your mobile phone, you'll need what is known as a SIM card.

A SIM card, or subscriber identity module card, contains your profile - in other words, your cell phone plan, features, contacts, text messages, and more. In fact, without a SIM card, you won't be able to use your carrier's cellular tower.

After all, you won't be authorized to make calls, use data, or send text messages.

There are several different types of SIM cards that are suitable for your smartphone and other devices such as tablets, smartwatches, GPS trackers, and more. Such devices probably won't need a SIM card capable of giving minutes and texts, so a specific data-only SIM card is what you should look for.

In this guide, we'll discuss what a data only SIM card is and what they're used for so you can connect your devices to the Internet. Use our comparison table to look at the best SIM cards.

Check Carrier Coverage

Prepaid data only SIM card benefits

We love Mobile Virtual Network Operators or MVNOs. If you're on the lookout for cheap cell phone plans, they're the best route to go down.

Want to stay on the same network, keep your phone and number, plus get greater flexibility?

Yep. You've got it. Forget the major carriers. Plans include everything you need, but come at a much better price with an MVNO.

  • Nationwide coverage: These cell phone carriers operate on the very same networks as the big four carriers.

  • High-speed data: Just because you're paying less, that doesn't mean you'll get lower speeds.

  • Much lower prices: Why are MVNOs so much cheaper? They don't have the huge overhead and advertising costs the big guys do.

  • No contracts: Don't get trapped into a two-year agreement. Switch carriers when you decide to with a no contract phone plan.

  • Bring your own device: You can bring your own device. No need to sign up for pricey device payments.

  • Customize your plan: You decide how much data you need. Pick the plan options that fit your budget - not the one your carrier thinks you need.

  • Great customer support: Smaller mobile providers are known for their attention to their customers. Stop feeling like an anonymous number getting lost in the crowd! Check out our carrier user reviews before switching.

What is a data SIM Card?

A data only SIM card is a SIM card that doesn't come with any minutes or text messages. You only receive data.

This type of prepay card is absolutely perfect if you need a tablet SIM card and you want to go online but there's no WiFi available.

Those who would use a data-only SIM card are mainly those who have a data-only device, like a tablet or a hotspot device. That way, they can access the internet in areas that WiFi is not accessible. For instance, say that WiFi is not accessible in a certain location in Maine, but the 4G LTE network is available.

Someone in need of internet access for business, school, etc. would then be able to secure mobile broadband internet via tablet or mobile hotspot and a bring your own phone plan. That way, the person can connect to the internet and check anything essential.

Data SIM card sizes

There are different sizes of SIM cards. What you need for a SIM card size is dependent on the device you own.

For instance, and according to GSM Arena, the Samsung Galaxy Tab 2 requires a Mini SIM (or Standard SIM). Then there is the iPad Air. The required iPad Air tablet SIM card is a Nano SIM. Other tablets require either a Micro SIM or a Standard SIM.

When you use our comparison table, you'll be able to see what size the SIM card comes in. Most SIM cards are 3-in-1 tricut, meaning that they're one size fits all. Simply cut the card to the size you need to fit the device. Before you buy a device, make sure you know what size SIM card you'll need to activate it.

Data only SIM card FAQs

Can I get a data only SIM card?

Yes. You can get a data only SIM card which is ideal for tablets and other Wi-Fi devices.

What is the best data only SIM?

The best data-only plan depends on how much data you need and your budget. Estimate how much data you really use so you're only paying for what you need.

Which is the best prepaid SIM card for data?

The best PAYG SIM for data depends on your budget and how much data you're looking for. Low-cost carriers have a great selection for all needs.

Recap

SIM cards are not just for mobile phones. Beyond cell phones, SIM cards are used in activity trackers, smartwatches, tablets, and more. But be sure when you purchase any of these devices to check for the SIM card size.

Also, when activating the SIM card, make sure to check your APN settings. Without the correct configuration of the APN settings, you may suffer from data issues.
