Access Codes
There are several access codes that are used by your
phone and its SIM card. These codes help you protect
the phone against unauthorized use.
The access codes (except for the PUK and PUK2
codes) can be changed using the Security Settings
menu options (5-3). See page 93 for further details.
Phone Password
The phone password can be set to avoid unauthorized
use of the phone. The password generally supplied
with the phone is 0000. You are advised to change it
before you start using your phone.
Keep the new password secret and in a safe place,
separate from the phone.
