PIN and PUK

The personal identification number (PIN) protects your SIM
card from unauthorized use. The PIN unblocking key (PUK)
unlocks the blocked PIN. Both the PIN and the PUK are
provided with the SIM card. For details, contact your service
provider.
SIM1 and SIM2 PINs are configured separately.
To enable the PIN lock, do the following:
Select Menu > Settings > Security settings > SIM1or
1.
SIM2 security > PIN lock.
Enter the PIN, and then press
2.
If you enter wrong PINs a specified number of times
consecutively, the phone prompts you to enter the PUK.
If you enter wrong PUKs a specified number of times
consecutively, the SIM card becomes permanently invalid. In
that case, contact your service provider for a new SIM card.
