PIN and PUK
The personal identification number (PIN) protects your SIM card from
unauthorized use. The PIN unblocking key (PUK) is used to unlock
the blocked PIN. Both the PIN and the PUK are provided with the
SIM card. For details, contact your service provider.
If you enter wrong PINs thrice consecutively, the phone prompts you
to enter the PUK.
If you enter wrong PUKs ten times consecutively, the SIM card
becomes permanently invalid. In this case, contact your service
provider for a new SIM card.
