My handset is asking for a PUK code
A PUK, or Personal Unlocking Key, is an 8-digit code that unlocks your SIM card if you can’t remember your PIN.
If your handset is asking you for a PUK Code, you will need to contact us to obtain the PUK Code.
You’ll have a maximum of 10 attempts to enter your PUK correctly. After 10 wrong attempts, your SIM will be permanently blocked. If this happens, you'll need a replacement SIM to continue using your mobile number.
