PIN code (4 to 8 digits)
The PIN (Personal Identification 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 enabled (Menu 4-6-1),
the code is asked each time the phone is switched on.
If you key in an incorrect PIN code three times in succession, key in
the PUK code and press OK. Key in a new PIN code and pressOK. Key
in the new code again and press OK.
