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 unauthorised use.
The access codes (except for the PUK and PUK2
codes) can be changed using the Security Settings
menu option. See page 94 for further details.
Phone Password
The phone password can be set to avoid unauthorised
use of the phone. The default password supplied with
the phone is 0000, but you are advised to change it
before you start using your phone. Keep the new code
secret and in a safe place, separate from the phone.
If you key in an incorrect password five times in
succession, the phone will not accept the correct
code for the next five minutes.
