NOTE:
Ability to use the network in this section relates to CSD
data calls only. HSCSD is not available in
every GSM
network and requires a supplementary roaming agreement between mobile operators for visiting
users to use HSCSD. Check with your home operator regarding the country or region in which you want to
roam. 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
A list of preferred networks is stored on the SIM card. This is typically set up by your mobile operator.
Preferred roaming partners are placed in the list so that you have the greatest range of available services
while roaming. When the home network is not available, the GC75 will check the available networks against
the preferred network list and select the one placed highest. Automatic network selection must be enabled.
You may change the networks in the preferred list.
If you want to add a new network:
1. Click
Add
and a new dialog box listing all the networks known to the GC75 PC Card appears on the
screen.
