We think Tesco Mobile's best value option on SIM only this March is their £14 a month plan below, which comes with 100GB data, plus unlimited minutes and texts on a 24‑month deal:

You can beat it for price if you don't need your SIM to be with a provider using the O2 network. But if that's a must, then it is the lowest-cost SIM with 100GB data or more. See the networks with cheaper plans here:

In our review of Tesco Mobile we said we liked the fact that you get access to O2’s great mix of coverage, as well as O2’s fast 5G network. They offer the same coverage experience as being on O2 directly.

They offer SIM only plans on 1-month, 12-month and 24-month contracts. You’ll generally get the best value per month by going with a longer contract, but you should compare plans to see if there are any special deals.

Price-wise they normally offer some good value mid-range data deals. Clubcard holders can get exclusive deals that are better than their usual range, but these are only on select tariffs. They’re cheaper than being on O2 directly.

The main benefit being on Tesco is that you can collect Clubcard points from shopping at Tesco stores to get money off your monthly bill and vice versa. They also offer a great inclusive EU roaming scheme.

Tesco Mobile will have your SIM delivered within 1-5 working days depending when you order and where you live, or you can take it directly from a Tesco store. You’ll get each size of SIM to fit any phone. Tesco don’t offer eSIMs (see networks that do).

You’ll have 14 days after your SIM arrives to return it if you’re not satisfied. You’ll get a full refund, even if you’ve used some of your data. Here’s how you can do it.

To get on a Tesco Mobile SIM contract you’ll have to pass a credit check. However, you can take one of their “Rocket Packs” which are monthly bundles of minutes, texts and data paid up front so you don’t need to pass a credit check.

To keep your number when switching to Tesco Mobile from another network, you can request a PAC from you current provider and sendt it to Tesco whenever.
