BT's best SIM only deals
Our best-rated BT Mobile SIM only deal this month
From all the options BT Mobile have got available this December on SIM only, we think this £20 12‑month deal is their best. For your £20 a month, you get 40GB data alongside unlimited minutes and texts:
While it's good enough to be in our pick of BT's best SIM only deals, other providers do still have similar plans for less, even ones that also use the EE network. See who's offering it for less here:
Their 6GB for £13 SIM is another good option
If you need less data, another good deal on BT Mobile at the moment is their £13 SIM only plan here, which includes 6GB data instead, plus unlimited minutes and texts:
It's definitely one of BT's best. But it's not market-leading. You can get a similar plan on other providers for less, even if you need your SIM to use the EE network. Here's where you can beat it on other networks:
BT's 5GB for £13 plan is a good option too
For a smaller amount of data, our next best pick of BT Mobile SIM only plans is their 24‑month £13 deal below, which gets you 5GB data and unlimited minutes and texts:

For people who need even more data, BT Mobile are also offering this £15 SIM, which includes 20GB data, unlimited minutes and texts on a 24‑month plan. It's another of their best deals:
