PIN and PUK
The personal identification number (PIN) protects your SIM
card from unauthorized use. The PIN unblocking key (PUK) can
unlock the blocked PIN. Both PIN and PUK are delivered with
the SIM card. For details, contact your service provider.
If you enter wrong PINs for a specified number of times
consecutively, the phone asks you to enter the PUK.
If you enter wrong PUKs for a specified number of times
consecutively, the SIM card is invalidated permanently. Contact
your service provider for a new one.
