Join the millions of people making the move to SIM-Only. SIM-Only works just the same as a mobile phone contract - you pay a fixed amount for a bundle of calls, texts and data each month. But because you already have a mobile it's much cheaper than a phone contract, with plans starting from as little as £9 a month.

And if you're looking for something simple and specific, Three have you covered there too, offering SIM contracts which just give you minutes, or texts, or data, at a bargain price. This way you'll only be paying for the things that you want. Our SIM plans are built for the internet – not only are they 4G ready, but our Plans come with generous data allowances and a guarantee that you'll never get a surprise data bill.
To transfer an old phone number over to 3 you will need to call your old network provider and ask for the unlocking code and PAC code for your phone (the PAC code will let you keep your old mobile number on your new SIM card). Using an old phone with your new SIM is very easy and takes no time at all - just stick the new SIM card into your unlocked handset, and before long you will be up and running with a phone that you love and a contract that couldn't be better.
