BT's best SIM only deals
The best SIM only deal on BT Mobile this month
Out of all the SIM only plans available this September on BT Mobile, we'd say their best value deal is their 12‑month SIM below, which gets you 50GB data, plus unlimited minutes and texts for £20 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. Here are other networks you can beat it on:
Unlimited minutes + Unlimited texts + 100GB data (5G) = £16 a month (12‑month contract)

Unlimited minutes + Unlimited texts + 100GB data (5G) = £15 a month (12‑month contract)

Or their £15 for 25GB SIM plan is worth a look too
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 25GB data, unlimited minutes and texts too:
If you don't need your SIM to be on a provider that uses the EE network, you can beat this deal elsewhere. But if you do, it's the cheapest 25GB data or more option. See the networks with cheaper plans here:
BT are also offering 15GB for £12 on SIM only
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 12‑month plan, comes with 15GB data, unlimited minutes and texts for £12 a month:
Compared to BT's other deals, this comes out among the best. But it's worth knowing you can get a lower price elsewhere, even on other providers that use the EE network. Here's which other networks can beat it:
They've also got a 6GB for £8 SIM plan at the moment
If you don't want so much data, have a look at BT Mobile's 6GB SIM below at £8 a month, as it's another good deal. It's on a 24‑month plan and comes with 6GB data, unlimited minutes and texts:
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 where you can get it for less here:
