Our Pay Monthly SIM Only plans give you a low-cost deal with lots of free stuff and a choice of contract length.
Getting started.
All you need is an unlocked phone to put your Three SIM into. We’ll show you how to unlock your phone and how to check if it’s 3G. We’ll also tell you whether your phone is compatible with Skype™ and Windows Live™ Messenger so you can get free calls and chats.
