(Optional) PIN and PUK
A Personal Identification Number (PIN) protects your UIM card from
unauthorized use. A PIN Unblocking Key (PUK) is used to change a
blocked PIN. If you enter an incorrect PIN a pre-defined number of
consecutive times, your UIM card will be locked and the phone asks
you to enter the PUK to unlock it. Both the PIN and the PUK are
supplied with the SIM card. For details, contact your service provider.
