Networks

Current Networks panel
From the Current Networks panel, you can retrieve the networks that are present in your location.
You also can select which of those networks you want to use.
To search for available networks
1. From the Telephony Settings view, select Current Network. The Current Networks panel
is displayed on the right.
2. Click Retrieve. The networks that are currently available are displayed in the Select a network
list box.
The available networks will fall into one of the following three categories:
• The home network.
• Available networks. These are networks that your home network operator has a roaming
agreement with.
• Forbidden networks. These are networks that you cannot use. Normally, you will not be able
to access these networks. You may try a forbidden network. If your home network has come
to an agreement that allows you to use the forbidden network, you will be able to access it.
To select another network
1. From the Telephony Settings view, select Current Networks. The Current Networks panel
is displayed on the right.
2. Click Retrieve. The networks that are currently available are displayed in the Select a network
list box.
3. Clear the Automatically choose a network for me check box.
4. In the Select a network list box, select the network that you want to use.
5. Click Apply to save the settings to your SIM card. The message Updating SIM card. Please wait
appears briefly on the window. If you are not allowed to use the network that you have chosen,
Forbidden is displayed.
Note:
GPRS, EDGE and UMTS roaming may be restricted, even on a network that is listed as
"Available". Contact your network operator to determine which are the appropriate roaming
networks to use.
