Out of the best SIM only plans on Tesco Mobile this September, we think the leading deal is their discounted 24‑month 60GB for £15 £14 one below, which also comes with unlimited minutes and texts:
£30 Clubcard voucher (automatic, no need to claim)It’s a total discount of £24 over the 24 months, when you add up the deal’s monthly £1 saving.
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:
Their unlimited data for £22 SIM is another good option

For those needing more data, another option for you on Tesco is their discounted 12‑month SIM below, which costs £30 £22 a month for unlimited data and comes with unlimited minutes and texts:
Add up that monthly saving of £8 over the full 12 months and you’re looking at a total discount of £96.
It might be one of Tesco's best deals on SIM only but you can get a lower price for a similar plan on other providers, even ones that use the O2 network. Here's which other networks can beat it:
Tesco's 12GB for £9.50 plan is a good option too

For a smaller chunk of monthly data, Tesco have got a discounted £11 £9.50 deal on SIM only we think's worth looking at. It gets you 12GB data, unlimited minutes and texts and it's a 12‑month plan:
If you add up the £1.50 monthly discount, you’ll save £18 in total over the full 12 months on the deal.
This is good for Tesco 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 O2 network. See where you can get it for less 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.
