SIM-only plans are simple. They give you all the data, calls and texts you need, but don’t have a phone attached. Every month, our expert deals hunters search out the best SIM-only plans to save you the most amount of cash.
SIM-only plans offer flexibility as they don’t tie you into lengthy contracts over many years. They can be changed readily depending on your needs, often with only 30 days’ notice. You can also easily change how much you want to spend every month.
These plans are best when you already have a phone you’re happy with, or prefer buying your device outright on sales days like Prime Day or Black Friday. As you’re not including the price of the phone in the monthly payments, the price is always much lower.

How to choose the best SIM
There are various factors to think about when considering a SIM-only plan:
Data: Using the phone for streaming, gaming, apps and surfing the web away from Wi-Fi can put a strain on your data allowance. It might be worth looking at your current usage, and seeing what you use or might need in the future when considering an upgrade. It’s always worth giving yourself a data cap that provides some wiggle room in relation to your average usage, just to ensure that you don’t have to incur additional costs if you happen to have a particularly data-heavy month.
Contracts: SIM deals usually have lesser lengths of service than all-in-one phone plans, typically 12-month or 30-day rolling plans, with the latter offering great flexibility. While there are 18-month and even 24-month options available, we recommend opting for a shorter length so that you’re not tied in for long if you’re ever dissatisfied with your service.
Networks: Most mobile phone networks nowadays offer a good coverage area, and it’s worth checking what works best in the usual places you’d be with your mobile. With that said, there are networks that run off the back of the usual EE, O2, Vodafone and Three that offer good service and at a lower price, such as Smarty and Voxi. Some networks also come with additional freebies and rewards services, including O2 Priority and Three Plus, so it’s worth doing a bit of comparison to see what you can get for your money.
