Change PIN / Find PUK code

The PIN code stops unauthorised use of your mobile phone and data. You need the PUK code to unblock a blocked SIM.

PIN: Use the PIN code to protect your mobile phone from unauthorised access. We recommend to always keep the PIN code activated. It comes with the SIM and you can change it at any time.

PUK: If you forget your PIN code and enter it incorrectly three times, your SIM will be blocked.

  • Enter your PUK code. Then follow the instructions on your device and select a new PIN code.

You can also find out about your PUK code in the Customer Center.
