center.
PIN and PUK
The personal identification number (PIN) protects your USIM 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
USIM card will become permanently invalid, and you must contact
your service provider for a new SIM/USIM card.
Both the PIN and the PUK are provided with your USIM card. For
details, contact your service provider.
