Three customers on pay monthly plans can get in touch with the company’s customer service division by calling 333 from their mobile. The call is free when made from their handset.

Alternatively, they can call 087 0733 0333 from any other phone and will be charged at their standard rate.

Pay as you go customers call 444 from their handset for free, or 087 0733 0333 from any other phone.

Three’s website is home to a extensive range of guides to help you to deal with everything from setting up your mobile phone, to procedures for if your mobile phone is lost or stolen.
