Note:
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)
Function support is network operator dependant.
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 whilst roaming. When the home network is not available, the GC79
will check the available networks against the preferred network list and select the one placed highest.
Automatic network selection must be enabled.
