Out of all the SIM only plans available this December on Three, we'd say their best value deal is their 12‑month SIM below, which gets you 100GB data, plus unlimited minutes and texts for £12 a month:

If you compare prices against Three's competitors, there are actually none with 100GB data or more that beat them currently. See the nearest SIM only deals from other networks under the dropdown below:

Three are also offering unlimited data for £16 on SIM only

To get more data, another good deal on Three at the moment is their £16 SIM only plan here, which includes unlimited data instead, plus unlimited minutes and texts:

This is good for Three 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 Three network. Here's where else you can get a lower price:

They've also got a 30GB for £12 SIM plan at the moment
