Status

Status

In each sub-menu (All calls, When roaming, etc.), the Status option allows you to know whether a type of call is barred or not.

Network

This menu allows you to handle the connection between the phone and the network, register manually the available networks and manage your preferred networks.

Change codes

Allows you to change your PIN and

PIN 2 codes, as well as the call Barring

Change codes code.

Depending on your SIM card, some features or options may require a PIN2 secret code. This is a second secret 4 to 8-digit code given to you by your operator.

If you enter a wrong PIN2 code 3 times, your SIM card is blocked. To unblock it, request the PUK2 code from your operator or retailer.

If you enter an incorrect PUK code 10 times in a row, the SIM card will be blocked and unusable. If this happens, contact your operator or retailer.

PIN protection

This allows you to set the PIN

protection On or Off. When On, you PIN protection will be asked to enter your PIN code

when switching your phone on.

You cannot change your PIN code if this option is Off.

GPRS attach

Your mobile integrates features that support GPRS (Global Packet Radio Service), a service allowing you to

exchange data with high speed rates and to stay always on-line (i.e. have a permanent connection to the Internet and WAP).

Contact your phone operator to have full information about GPRS availability over their network and for an appropriate subscription. You might also need to configure your phone with the GPRS settings supplied by your operator, by using the menus described in this section.

This menu allows you to define the attach mode of your mobile phone to the GPRS service:

Always on

Your phone will always register to the GPRS service. This option allows faster GPRS connection. However it will increase energy consumption.
