Looking at what you can get on SIM only with BT Mobile this October, our best-rated deal would be their 12‑month plan below, which comes with 60GB data, plus unlimited minutes and texts for £20 a month:

While this is a good enough deal to make it into the best of BT's SIMs, you can beat it for price (even if you definitely want a provider that uses the EE network). See lower-priced networks' deals here:

Their £15 for 30GB plan is a decent deal for October

If you need less data, you might like the £15 SIM only deal running on BT Mobile at the moment. It's a 12‑month plan, which comes with 30GB data, unlimited minutes and texts too:

It's actually possible to beat this deal if you're not fussed whether your SIM is with a provider using the EE network. But if you are, it is the current best-priced option. Here are other networks you can beat it on:

They're also offering 5GB for £8 on SIM only currently

For a smaller amount of data, we'd say this is one of BT's best deals on SIM only this month too. It's a 24‑month plan, comes with 5GB data, unlimited minutes and texts for £8 a month:

In comparison to the rest of BT's current SIM only plans, it's one of the best. But it is beatable on price, even if you're set on joining a provider that uses the EE network. See the networks with cheaper plans here:
