Top-up your Pay As You Go phone.

Here we explain the different ways to top-up your Pay As You Go phone on Three. If you're looking for help on topping up your Mobile Broadband dongle or MiFi wireless modem you can find it here.

Once you've topped up your account make sure you convert your credit to an Add-on to get even more for your money. Find out how here. If you've just bought a new Pay As You Go phone from us, it'll already be preloaded with an All-in-One 10 or All-in-One 15 Add-on.
