PIN and PUK
The personal identification number (PIN) protects your UIM card
from unauthorized use. The PIN Unlock Key (PUK) is used to
unlock the blocked PIN.
If you enter wrong PINs three times consecutively, the phone
prompts you to enter the PUK. If you enter wrong PUKs 10 times
consecutively, the UIM card becomes permanently invalid. In this
case, contact your network operator for a new UIM card.
The PIN and the PUK are provided with your UIM card. For details,
contact your network operator.
