PIN and PUK
The personal identification number (PIN) protects your SIM
card from unauthorized use.
If you incorrectly enter the PIN a specified number of times, the
PIN is blocked and the phone prompts you to enter the PIN
unblocking key (PUK). If this occurs, enter the PUK to unblock
the blocked PIN.
If you incorrectly enter the PUK a specified number of times,
the SIM card will become permanently invalid, and you must
contact your service provider for a new SIM card.
Both the PIN and the PUK are provided with the SIM card. For
details, contact your service provider.
