Choosing another network:

1.Uncheck Automatically choose a network for me.

2.Select the network that you want to use.

3.Click Apply to transfer the setting to your GC89.

The message Please wait appears briefly on the screen. If you are not allowed to use the network that you have chosen, Forbidden is displayed.

Note:

GPRS is commonly available in GSM networks, but fewer roaming agreements are in place. You may therefore need to explicitly select one of the available networks in order to use GPRS when abroad. Check with your home operator to find out which networks are GPRS roaming partners in the country or region in which you want to roam.

Preferred Network

Note:

This option is only available if your operator provides it.

A list of preferred networks is stored on the SIM card. This is typically set up by your mobile operator as part of SIM manufacture. Preferred roaming partners are placed in the list so that you have the greatest range of available services when roaming. When the home network is not available, the GC89 will check the available networks against the preferred network list and select the one placed highest. Automatic network selection must be enabled.

If you want to add a new network:

1.Click Add. A new dialog with all the networks known to the GC89 appears on the screen.

2.Select the network that you want to add and click OK.

3.Click Apply to transfer the setting to your GC89 SIM card.

If you want to delete a network from the list:

1.Select the network that you want to delete.

2.Click Remove.

3.Click Apply to transfer the setting to your GC89’s SIM card. If you want to re-arrange the order of the networks listed:

1.Select the network that you want to move.

2.Click the Move Up or Move Down arrows to rearrange the order.

3.Click Apply to transfer the setting to your GC89’s SIM card.

Note:

If the list of preferred networks is full, the Add button is disabled (grey).

Frequency Band

GSM operates in a number of different frequency bands. 900 and 1800MHz are used in Europe, Asia, Australia and Africa, while 850 and 1900MHz are used in North and South America.

By default your GC89 will operate in 'quad-band' mode and automatically find available networks in any of these frequency bands. It is not recommended to change this setting.
