How 1pMobile’s benefits and SIM only deals compare
In our full review of 1pMobile we rated them very highly for offering full access to EE’s network for calls (3G/2G) and data (4G/5G). On top of that they also have an excellent WiFi/4G calling scheme.
All their SIM only plans are on 1-month deals. They offer a wide range of data plans and sometimes share even better hidden deals with comparison websites like us, so keep an eye out.
1pMobile offer some of the cheapest deals on EE’s network without stripping out WiFi calling and over-the-phone customer service like the other providers on EE do.
They also include EU roaming in these 46 EU countries on all plans. You can get extra rewards for bringing friends onto 1pMobile as well, and if you ever need extra data their add-ons are quite good value.

Useful information about 1pMobile’s SIM only plans
Your 1pMobile SIM package will be delivered within 1-3 working days via Royal Mail. You’ll receive each size of SIM to pop into any phone. 1pMobile don’t currently offer eSIMs (see the networks that do here).
If you’re unhappy with your SIM you have 14 days to return it to get a full refund. They’ll even give you back any credit you topped up your SIM with (see their full terms and conditions).
Since you pay for your mins, texts and data up front you don’t need to pass a credit check to join 1pMobile. That makes them a great choice if you’ve been rejected for a contract on EE.
To keep your number when switching over to 1pMobile, you’ll have to request a PAC from your old network and send it to 1pMobile at any time. Here’s their full guide on how to do this.
