12GB SIM only deal on Three just £6

12GB of data should be the perfect balance for many people – plenty available for streaming music, web browsing, and using social media, but not the overkill of a 100GB or unlimited allowance. And right now, you can get 12GB of data on Three for hardly any money at all. 

We have an exclusive SIM only deal granting you 12GB of data for just £6 per month. That’s down from a standard price of £14 per month, so you’re saving £8 per month, and as this is a 12-month contract, you save £96 over the life of the contract.

This plan also comes with unlimited minutes and texts, with 5G available as standard, and you also get access to Three+ Rewards, giving you discounts and freebies at various brands, along with competitions. 

But if 12GB isn’t the right allowance for you, we also have a 3GB deal for £5 per month, and a 30GB deal for just £8 per month, among other exclusive offers. 

You won’t get any of these deals if you go to Three direct, so click through our links to save big money.

How much is 12GB data?

12GB of data is a pretty decent allowance which enables you to use social media for 4 hours a day, or browse the internet for 6 hours a day. However, those who want to do heavy video or music streaming should consider a higher data allowance. Read our how much data do I need guide to find out more.
