access codes (except PUK and PUK2 codes) can be
changed by using the
Change codes feature
[Menu-4-4-6]. See page 52.

The PIN (Personal Identification Number) code
protects your SIM card against unauthorised use. The
PIN code is usually supplied with the SIM card. When

on. When the
PIN code request is set to Off , your phone
connects to the network directly without the PIN code.
