All about Add-ons
Getting an Add-on
It’s really easy to choose your Add-on using the Three app, or you can go online. The best way to top-up or buy an Add-on is on our dedicated top-up webpage. No need to log in - just enter your phone number and payment details. You can also buy a top-up voucher in any store where you see the top-up logo, and you can add it to your account using our top-up or buy an Add-on page.
Add-ons vs 321 rates
Get more data, minutes and texts for a fixed price with Add-ons. You can choose from a £10 Add-on, all the way up to a £90 Add-on, and you’ll get unlimited minutes and texts, with your chosen amount of data.
You can also earn Pay As You Go Rewards points whenever you buy an Add-on, which you can use in our wuntu app. Want to know more? Check our Check our frequently asked questions.
