Out of the best SIM only plans on Coop Mobile this November, we think the leading deal is their discounted 1‑month 100GB for £23 £18.40 one below, which also comes with unlimited minutes and texts:
You’ll save £55.20 if you stayed on the deal a whole year, adding up that £4.60 monthly saving.
While this is a good enough deal to make it into the best of Coop's SIMs, you can beat it for price (even if you definitely want a provider that uses the EE network). Here's where else you can get a lower price:
Coop are also offering 30GB for £13.60 on SIM only

For less data to use each month, Coop Mobile are also offering this discounted £17 £13.60 SIM, which includes 30GB data, unlimited minutes and texts on a 1‑month plan. It's another of their best deals:
It’d be a total discount of £40.80 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. See who's offering it for less here:

If you wouldn't get through that much data, you might like the discounted £11 £8.80 SIM only deal running on Coop Mobile at the moment. It's a 1‑month plan, which comes with 3GB data, unlimited minutes and texts too:
Stick on the deal for a whole year and that monthly saving of £2.20 would add up to a total discount of £26.40.
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. Here's where you can beat it on other networks:

To get a bigger data allowance, we'd say this is one of Coop's best deals on SIM only this month too. It's a discounted 1‑month plan, comes with 10GB data, unlimited minutes and texts for £13 £10.40 a month:
If you add up the £2.60 monthly discount over the course of a year, you’d save £31.20 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. See lower-priced networks' deals 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).
