5.35.5.3 Network Configuration

Note: Network configuration is not available with CDMA modems.

In the main Wireless WAN screen:

•Tap on the Tools menu, and choose Network.

By default the GSM radio modem automatically chooses from the available and allowed networks (allowed networks are the home network and all other networks with which the home network has a roaming agreement). You may find there are some situations in which you want to override this default behaviour. For example, you may want to disable roaming if you find yourself in a border area where the home network is not available but a foreign roaming partner is available. Abroad, you may find that an available network does not have packet data roaming agreements. In this case, you’ll need to manually select the network which you know to support packet data roaming.

Automatic network selection is enabled or disabled by checking or unchecking Enable automatic network select in the Network dialog box. When automatic network selection is disabled, you must select a network manually.

Available networks can also be viewed without changing any settings. Scanning for available networks is a lengthy operation – a progress bar is shown while the scan is active. For every network that is found, the network name, country, status and numeric network identifier (MCC/MNC, Mobile Country Code followed by the Mobile Network Code) is displayed.

Note: Your home network operator will need to let you know which other net- works have roaming agreements. Even when a network is listed with an ‘Available’ status, it does not necessarily follow that it can be used or that the roaming agreement covers packet data.

A status of ‘Forbidden’ indicates that the network cannot be used. If you choose a network that is not covered by a roaming agreement, the status in the main WWAN dialog box changes to ‘Emergency calls only’, ‘No net- work found’, ‘GPRS not available’ or ‘GPRS not allowed’.
