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.
To enable the PIN lock, do the following:
Tap Menu > Settings > Security settings > SIM lock.
1.
Tap the text box to open the onscreen keypad, enter the PIN,
2.
tap and then OK.
If you enter incorrect PINs for a specified number of times
consecutively, the phone prompts you to enter the PUK.
If you enter incorrect PUKs for a specified number of times
consecutively, the SIM card becomes permanently invalid. In
this case, contact your service provider for a new SIM card.
