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.
The PIN lock for each SIM card must be configured separately.
To enable the PIN lock:
Select Menu > Settings > Security settings > PIN > SIM1, SIM2, or
1.
SIM3 > On.
Enter the PIN, and press
2.
or (OK).
