PUK
The 8-digit PUK (Personal 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, proceed as follows.
1. Key in 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 is
displayed, key in 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.
