For people who don't need that much data, we'd say this is one of BT's best deals on SIM only this month too. It's a 12‑month plan, comes with 15GB data, unlimited minutes and texts for £12 a month:

It might be one of BT's best deals on SIM only but you can get a lower price for a similar plan on other providers, even ones that use the EE network. See the networks with cheaper plans here:

They're also offering 1GB for £6 on SIM only currently

If that'd be too much data for you, have a look at BT Mobile's 1GB SIM below at £6 a month, as it's another good deal. It's on a 24‑month plan and comes with 1GB data, unlimited minutes and texts:

This is good for BT but it's not an unbeatable price. You can get similar SIM only plans for less with some other providers, even ones that also use the EE network. Here's which other networks can beat it:
