unauthorized use. The PIN unlocking key (PUK) can unblock the
blocked PIN. Both PIN and PUK are delivered with the UIM card.
For details, consult your service provider.
If you enter wrong PINs for a specified number of times
consecutively, the phone asks you to enter the PUK code.
If you enter wrong PUKs for a specified number of times
consecutively, the UIM card is invalidated permanently. Contact your
service provider for a new card.
