If you need to unblock your phone, you'll need an 8 digit PUK (Personal Unblocking Key) code from us. Please give us a call on 0333 300 3333 (standard rates apply) and we'll give this to you.
Once you enter your PUK code you'll be asked to enter a new PIN which is a four digit number of your choice.
You have 10 chances to get enter the PUK code correctly. After that your SIM will be blocked. So if the PUK code hasn't worked after the second attempt, it's best you call us and we'll be able to help you.
