Their £9 for 12GB plan is a decent deal for December

For a smaller chunk of monthly data, Tesco's £9 SIM below is another of their best deals this month. For £9 a month, it offers 12GB data, unlimited minutes and texts on a 24‑month plan:

This isn't the very cheapest deal with 12GB data or more out now. But if you definitely need a SIM only plan that uses the O2 network, we think it is the best option. See the networks with cheaper plans here:

They're also offering 2GB for £7.50 on SIM only currently

If you don't need that much data, the next best SIM only plan on Tesco Mobile in our opinion is their 12‑month one below. For £7.50 a month, you get 2GB data, plus unlimited minutes and texts:

While it's good enough to be in our pick of Tesco's best SIM only deals, other providers do still have similar plans for less, even ones that also use the O2 network. Here's which other networks can beat it:

How Tesco Mobile’s benefits and SIM only prices compare

Review stars with a hand pointing

We go over all of Tesco’s benefitsRead our full review

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.

You can take a 1-month, 12-month or 24-month contract. Usually, the longer the contract the less you’ll pay each month, but it’s worth comparing plans here to check for any special deals on different plans.

Tesco tend to offer good value on mid-range data plans. And if you’ve got a Clubcard you can get better value deals than their regular range, but only on certain tariffs. They typically offer better value than O2.

One massive benefit is that you can collect Clubcard points from shopping at Tesco stores to get money off your monthly bill and vice versa. And you get extra benefits for adding other users onto your account.

Your Tesco Mobile SIM will be delivered within 1-5 working days (depends where you live and when you ordered). Or you can take one from a Tesco store. You’ll get every size of SIM, but you can’t get an eSIM.

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 join any Tesco SIM only contract you’ll have to pass a credit check. If you’ve got a bad or no credit history you can still join them by taking out a “Rocket Pack” which are bundles of mins, texts and data.

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