Menu functions

Network selection (Menu 3.4)

This network service allows you to either automatically or manually select the network used when roaming outside of your home area.

You can select a network other than your home network only if there is a valid roaming agreement between the two.

•Automatic: connect to the first available network when roaming.

•Manual: select the network you want.

Caller ID (Menu 3.5)

This network service allows you to prevent your phone number from being displayed on the phone of the person being called. However, some networks do not allow the user to change this setting.

•Default: use the default setting provided by the network.

•Hide number: ensure your number does not display on the other person’s phone.

•Send number: send your number each time you make a call.

Band selection (Menu 3.6)

For the phone to make and receive phone calls, it must register with an available network. Your phone can handle any of the following types of networks: GSM 1900 and Combined GSM 900/1800.

The country where you purchased your phone determines the default band that it uses. When you travel abroad, you must remember to change to an appropriate band.

When you select a new band, your phone automatically searches for all available networks. Your phone registers with a preferred network within the band.

Active line (Menu 3.7)

Some SIM cards may be used with two subscriber numbers. Use this menu to select the line to be used to make calls, if your SIM card supports two numbers.

Calls come in on both lines, regardless of the selected line.
