PIN and PUK
The personal identification number (PIN) protects your SIM card
from unauthorized use. The PIN unblocking key (PUK) can unlock
the blocked PIN. Both PIN and PUK are delivered with the SIM card.
For details, contact your service provider.
If you enter wrong PINs for a specified number of times
consecutively, the phone asks you to enter the PUK.
