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 in case you
have lost it, please contact your service provider.
To re-enable your PIN, proceed as follows.
1. Key-in the PUK and press the OK key.
2. Enter a new PIN of your choice and press the
OK key.
3. When the Confirm New PIN message is
displayed, key-in the same code again and
press the OK key.
If you enter an incorrect PUK ten times in succession,
the SIM card becomes invalid. Please contact your
service provider for a new card.
Pin Password
The 4 ~ 8 digits of password is required when you
use the Call barring function. You can obtain the
password from your service provider when you
subscribe to this function.
