What to do if your phone asks for a PIN or PUK

A PIN protects your SIM  card. If you forget your PIN or enter it incorrectly too many times you may be blocked from using it. To get it back up and running, you need to get a Personal Unblocking Key (PUK)

• Don't try to guess the PUK - if you enter the wrong PUK too many times, you may have to get a new SIM card.
• To set up or deactivate a PIN, look in your phone's user manual.
