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.Switch & Save $600/yr - Calculate Your Savings
What Is a 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.
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.
Smart Device SIM
SIM cards are not just for mobile phones. Beyond cell phones, SIM cards are used in activity trackers, smart watches, 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.
