PIN
The Personal Identification Number or PIN (4 to 8 digits) protects
your SIM card against unauthorized use. It is usually supplied with
the SIM card.
If you enter an incorrect PIN three times in succession, the code is
disabled and cannot be used until you re-enable it by entering the
PUK (see below).
PUK
The 8-digit PUK (PIN Unblocking Key) is required to change a
disabled PIN. The PUK may be supplied with the SIM card. If not, or
you have lost it, contact your service provider.
To re-enable your PIN:
1. Enter the PUK and press the OK soft key.
2. Enter a new PIN of your choice and press the OK soft key.
3. When the Confirm New PIN message displays, enter the same
code again and press the OK soft key.
If you enter an incorrect PUK ten times in succession, the SIM card
becomes invalid. Contact your service provider for a new card.
