We've taken each of Three's best SIM only plans this month and compared them on price with other UK networks. Here's what we found. SIM Sherpa is your trusty guide. Last updated: 11th January 2022.

Three's best SIM only deals

Out of all the SIM only plans available this January 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 £15 a month:

It's definitely one of Three'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 Three network. See who's offering it for less here:

Their 30GB for £10 SIM is another good option

Three's unlimited data for £16 plan is a good option too

If you need even more data, Three are also offering this £16 SIM, which includes unlimited data, unlimited minutes and texts on a 12‑month plan. It's another of their best deals:

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

Their £5 for 2GB plan is a decent deal for January

If you need less data, you might like the £5 SIM only deal running on Three at the moment. It's a 12‑month plan, which comes with 2GB data, 200 minutes and unlimited texts too:

It's a good enough deal to get into Three's best SIMs but you can actually get a lower price for a similar plan elsewhere, even if you definitely want it to use the Three network. Here are other networks you can beat it on:
