A data only SIM is a SIM card that comes with a data allowance per month, but no minutes or texts. They are used primarily in tablets, mobile wifi and dongles which don't make or receive calls.
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).
All the major UK mobile networks offer data only SIM deals including EE, Three, O2, Vodafone and BT Mobile. They all come with 4G included at no extra cost, but currently there are no networks offering data only SIM plans with 5G data.
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 standard 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.
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.
Yes, you can put a data only SIM in a phone, but be aware you won't have any allowances to make calls or texts. Any calls or texts you do make may be charged at full standard out of allowance rates.
