Out of all the SIM only plans available this December on Coop Mobile, we'd say their best value deal is their discounted 1‑month SIM below, which gets you 100GB data, plus unlimited minutes and texts for £23 £18.40 a month:
That £4.60 monthly saving vs full price will save you £55.20 in total over the course of a year.
If you're open to joining other networks than Coop, you can actually get a similar deal for less, even with providers whose SIMs also use the EE network. Here are the networks where it'd cost less:

For less monthly data, Coop have got a discounted £17 £13.60 deal on SIM only we think's worth looking at. It gets you 30GB data, unlimited minutes and texts and it's a 1‑month plan:
It’s a discount of £3.40 a month against the full price, adding up to a £40.80 saving over a year.
While it's good enough to be in our pick of Coop's best SIM only deals, other providers do still have similar plans for less, even ones that also use the EE network. See which networks that are cheaper here:

If you need less data, we think this discounted 3GB 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 £11 £8.80 a month:
That discount will save you £2.20 a month, which would add up to £26.40 over the course of a year.
It's definitely one of Coop's best. But it's not market-leading. You can get a similar plan on other providers for less, even if you need your SIM to use the EE network. Here's where else you can get a lower price:

To get more data, we also think this discounted £13 £10.40 Coop Mobile SIM is one of their best options. It comes with 10GB data, unlimited minutes and texts on a 1‑month deal:
That’s £31.20 you’d save over a year on the same deal, thanks to the £2.60 monthly discount.

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).
