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).
