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. See page 155 for further
details.

Phone password

The Phone lock feature (see page 156) uses the
phone password to protect your phone against
unauthorised use.
The phone password supplied with the phone is
preset to "00000000" at the factory. To change the
password, use the Change password menu
option. See page 157.

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 155), you must
enter the PIN each time you switch on the phone.
If you key in an incorrect PIN three times in
succession, you will have to 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.

press the OK soft key to unlock the phone. Key in a
new PIN2 and press the OK soft key. Key in the new

The PUK (PIN Unblocking Key) is required to change
a blocked PIN. The PUK may be supplied with the
SIM card. If not, contact your local service provider.

succession, the SIM card cannot be used anymore.
Contact your service provider for a new card.
