PIN and PUK
The personal identification number (PIN) protects your Smart card from
unauthorized use. The PIN Unlock Key (PUK) is used to unlock a 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 Smart
card becomes permanently invalidated. In this case, contact your network
operator for a replacement.
The PIN and the PUK are provided with your Smart card. For details, contact
your network operator.
