Tesco Mobile SIM only deals for September: comparing their prices

This month's overall best Tesco Mobile SIM only deal

Tesco Mobile's best SIM only plan this September in our opinion is their £13, 24‑month deal below, which comes with 60GB data, plus unlimited minutes and texts for your money:

Unlimited minutes + Unlimited texts + 0MB 60GB data (5G) = £15 £13 a month (24‑month contract)
£20 Clubcard voucher (automatic, no need to claim)

🛈 No annual price rise for Clubcard holders

It might not be the lowest-cost SIM only deal with 60GB data or more on the entire market but if you're sure you need a SIM using the O2 network, it is the best-priced. See lower-priced networks' deals here:

Their £9 SIM with 12GB is our next favourite this September

If that's more data than you need, we'd say this is one of Tesco's best deals on SIM only this month too. It's a 24‑month plan, comes with 12GB data, unlimited minutes and texts for £9 a month:

Unlimited minutes + Unlimited texts + 0MB 12GB data (5G) = £10 £9 a month (24‑month contract)
See full deal

🛈 No annual price rise for Clubcard holders

If you don't need your SIM to be on a provider that uses the O2 network, you can beat this deal elsewhere. But if you do, it's the cheapest 12GB data or more option. Here are other networks you can beat it on:

We also like their £25 for unlimited data plan

If you think you'll need even more data, have a look at Tesco Mobile's unlimited data SIM below at £25 a month, as it's another good deal. It's on a 24‑month plan and comes with unlimited data, unlimited minutes and texts:

Unlimited minutes + Unlimited texts + 0MB Unlimited data (5G) = £0 £25 a month (24‑month contract)

🛈 Monthly price will increase each April by the Consumer Price Index rate of inflation published in January + 3.9%

Compared to Tesco's other deals, this comes out among the best. But it's worth knowing you can get a lower price elsewhere, even on other providers that use the O2 network. See the networks with cheaper plans here:

How Tesco Mobile’s benefits and SIM only prices compare

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.

Handy information about Tesco’s SIM only plans

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.
