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.
Some access codes can be changed using the
Security menu option (Menu 4.4). See page 111
for further details.
Phone Password
The Phone lock feature (see page 112) uses the
phone password to protect your phone against
unauthorised use.
The phone password is supplied with the phone and
is preset to “00000000” at the factory. To change
the password, use the Change password menu
option (Menu 4.4.4). See page 112.
PIN
The PIN (Personal Identification Number) protects
your SIM card against unauthorised use. It is
usually supplied with the SIM card. When the PIN
Check feature is enabled (see page 111), you must
enter the PIN each time you switch on the phone.
If you key in an incorrect PIN three times in
succession, key in the PUK and press the Ok soft
key to unlock the phone. Key in a new PIN and
press the Ok soft key. Key in the new PIN again and
press the Ok soft key.
