SIM only deals

1. Three’s unlimited data SIM bargain:

The best SIM plan around

Three SIM | 12 months | Unlimited data, calls and texts | £16 per month
This deal appeared over Black Friday and is still dominating the market. It costs just £16 a month while supplying a completely unlimited data, calls and texts cap. That’s the cheapest 5G unlimited SIM on the market and the lowest Three has ever gone. Or you can get the same contract for £1 less with Smarty, if you don’t mind sacrificing 5G access.

3. The best EE SIM plan around:

4. Super cheap SIMs with Lebara

5. flexible and cheap SIM plans with Smarty:

SIM only deal from Smarty | 1 month rolling | 30GB data | Unlimited calls and texts | £10 per month
Like the Lebara deal above, Smarty works on 1-month rolling contracts across all of its plans. This means you can leave at any time, using it as a long term option or a quick stop-off. This deal in particular offers you 30GB of data while only charging £10 a month for it. That’s the best amount of data you’ll be able to get for a price as low as that.
