Co-op's best SIM only deals
The SIM only deal on Coop Mobile we rate highest this month

We think Coop Mobile's best value option on SIM only this February is their discounted £23 £18.40 a month plan below, which comes with 100GB data, plus unlimited minutes and texts on a 1‑month deal:
It’d be a total discount of £55.20 if you stayed on the deal for a whole year.
It's a good enough deal to get into Coop's best SIMs but you can actually get a lower price for a similar plan elsewhere, even if you definitely want it to use the EE network. Here's where you can beat it on other networks:
Coop's 30GB for £13.60 plan is a good option too

If you wouldn't get through that much data, we think this discounted 30GB is one of the best SIM only plans on Coop Mobile too. It's on a 1‑month deal, comes with unlimited minutes and texts - all for £17 £13.60 a month:
Stick on the deal for a whole year and that monthly saving of £3.40 would add up to a total discount of £40.80.
In comparison to the rest of Coop's current SIM only plans, it's one of the best. But it is beatable on price, even if you're set on joining a provider that uses the EE network. See lower-priced networks' deals here:
Their £8.80 for 3GB plan is a decent deal for February

For a smaller chunk of monthly data, we also think this discounted £11 £8.80 Coop Mobile SIM is one of their best options. It comes with 3GB data, unlimited minutes and texts on a 1‑month deal:
If you add up the £2.20 monthly discount over the course of a year, you’d save £26.40 in total on the deal.
It does enough to get into our pick of Coop's best SIMs but that doesn't mean it's unbeatable on price. Other providers (even ones that use the EE network) can beat it. Here are other networks you can beat it on:
They're also offering 10GB for £10.40 on SIM only currently
just
£10.40

To get a bigger chunk of data, Coop's discounted £13 £10.40 SIM below is another of their best deals this month. For £10.40 a month, it offers 10GB data, unlimited minutes and texts on a 1‑month plan:
That £2.60 monthly saving vs full price will save you £31.20 in total over the course of a year.
Compared to Coop'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 EE network. See the networks with cheaper plans here:

How Co-op Mobile compare for SIM only prices and benefits
Co-op Mobile are a smaller provider that use EE’s network for call (3G/2G) and data (4G/5G) signal. That’s great considering EE have the best 4G and 5G coverage of all networks.
All their SIM only plans are sold as 1-month contracts that let you switch plans each month as you need. Their plans tend to be fairly expensive, but it’s worth comparing deals to find the best one for you.
They still tend to offer better value deals than joining EE directly, but there are some cheaper providers that also use EE networks (see them all here).
You can use your UK plan in these EU destinations at no added cost. And there are no limits to your data usage while roaming in the EU. Otherwise, Co-op are largely a low-frills provider.

Other things to know about Co-op’s SIM only prices
Your Co-op Mobile SIM only package will be delivered within 2-3 days of ordering. It will contain every size of SIM to pop into any phone. But Co-op don’t offer eSIMs (see the networks that do here).
If you’re unhappy with your SIM you can return it within 14 days to get a full refund (read the full terms and conditions here).
Since you’re signing up to a contract you will have to pass a credit check to join on any Co-op SIM only plan. If you fail this check there are other networks on EE that don’t make you pass a credit check to join.
To keep your number when switching from your current provider to Co-op you’ll have to request a PAC from your old network and give it to Co-op at any point (here’s their guide to how it works).
