For almost an entire year, Three has offered the UK’s cheapest unlimited data SIM. It dropped its pricing all the way down to just £16 a month for last year’s Black Friday deals. Since then, it has held firm.
The only network that is able to match that price is Smarty, which also holds £16 pricing but only until the end of September. Where Three gets the edge on Smarty is that it offers 5G with its SIM.
This makes it the perfect option if you have a 5G handset like the iPhone 12, Samsung Galaxy S21 or Google Pixel 5. You can find out more about this offer below or head to our SIM only deals guide to see the other great options around right now.
