If unauthorized access to the device is a concern, the Require PIN on resume checkbox 
should be checked. In this case, you will be prompted whenever a PIN is required and the 
PIN is not stored.
5.36.5.3 Network Configuration
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 auto-
matic 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 avail-
able 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 identi-
fier (MCC/MNC, Mobile Country Code followed by the Mobile Network Code) is 
displayed.
Note: Network configuration is not available with CDMA modems.
Note: Your home network operator will need to let you know which other networks 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 cov-
ers 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 network found’, ‘GPRS not 
available’ or ‘GPRS not allowed’.
