PIN Code (4 to 8 digits)
The PIN (Personal Identity Number) code protects your SIM card against
unauthorised use. The PIN code is usually supplied with the SIM card.
When the PIN code request is set to on within menu PIN Code Request
(Menu 4 1), the PIN code is asked each time the phone is switched on.
If you enter an incorrect PIN code three times in succession, you will be
asked for a PUK code. Key in the PUK code and press (OK). Then enter
a new PIN code and press (OK). Then enter the new code again at the
prompt Verify new code: and press (OK).

able if supported by your SIM card.
If you enter an incorrect PIN2 code three times in succession, you cannot
use the functions which require the code before entering the correct
PUK2 code. Enter the PUK2 code once and then enter a new PIN2 code
twice.

service provider.
If you enter an incorrect PUK code ten times in succession, the SIM card
becomes invalid. Contact your service provider for a new card.
