Tesco best SIM only deals
This month's best SIM only deal on Tesco Mobile
Out of all Tesco Mobile's SIM only plans they've got running this September, our current best pick would be their £16 one below. It's on a 24‑month deal, gets you 100GB data, plus unlimited minutes and texts as well:
It can actually be beaten on price if you don't need your SIM to be with a provider that uses the O2. If you do need that, it is the cheapest SIM with 100GB data or more. Here's which other networks can beat it:
Or their £11 for 30GB SIM plan is worth a look too
If you wouldn't get through that much data, our next best pick of Tesco Mobile SIM only plans is their 24‑month £11 deal below, which gets you 30GB data and unlimited minutes and texts:
If you're open to joining other networks than Tesco, you can actually get a similar deal for less, even with providers whose SIMs also use the O2 network. See where you can get it for less here:
Tesco are also offering 2GB for £7.50 on SIM only
For a smaller chunk of monthly data, Tesco Mobile are also offering this £7.50 SIM, which includes 2GB data, unlimited minutes and texts on a 12‑month plan. It's another of their best deals:
Unlimited minutes + Unlimited texts + 2GB data (5G) = £7.50 a month (12‑month contract)

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 are the networks offering it cheaper:

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.
