A Data Only SIM is the ideal choice if you have a tablet (with a SIM card slot), mobile broadband device or other device that you want to get online when away from Wi-Fi, but which you don’t need to call or text from, because, as the name suggests, a Data Only SIM comes with a data allowance but no minutes or texts.
All plans come with 4G, so you can enjoy fast downloads and rapid internet browsing. You can also share internet with any other device that has supports WiFi over a personal hotspot (or tethering).
You can get a Data Only SIM deal on any of the following networks:
You’ll probably need a Nano SIM, which is the smallest type of SIM card and is used in the majority of devices from the last few years. However, it’s possible that you’ll need a Micro SIM or possibly even a full-size SIM card.
Check the documentation for your device to find out for sure, or search for the make and model online.
However, most networks send a trio or multi SIM which includes all of the possible sizes, so you don’t need to check which you need before placing an order.
There are several things to bear in mind when choosing a Data Only SIM network. First there’s cost, which you can compare by checking any of the deals on this page, but just as important is coverage, which we give an overview of below. Then you might also want to consider what its roaming terms are, which we also give an overview of below.
Every UK network has comprehensive 3G coverage, while 4G coverage is now widely available in most places as well. The most up to date figures provided by the networks are below.

All UK networks are required to allow you to roam across the EU at no extra cost. However, Three stands out by also allowing Data Only SIM customers to roam further afield in locations such as the US and Australia.
EE also allows you to take your allowances beyond Europe, but only if you’re on a 4GEE Max plan, in which case you can also roam in the US, Canada, Mexico, Australia and New Zealand.
