Network
You can customise settings for network services supported by
your service provider. The following options are available:
• Network mode: Select the network mode in which your
phone operates.
Dual mode: the phone operates in the GSM or UMTS
network automatically.
UMTS: the phone operates in UMTS (3G) networks. You
can get higher speed quality than on lower generation
networks, and use advanced data and information services,
such as video calls.
GSM: the phone operates in the GSM 900/1800 or 1900
network.
• Operator selection: Choose Automatic to set the phone
to automatically search for and select one of the cellular
networks available in your area, or Manual to select the
desired network manually from a list of networks. The
selected network must have a roaming agreement with
your home network, that is, the operator whose USIM/SIM
card is in your phone.
Tip: A roaming agreement is an agreement between two or
more network service providers to enable the users of one
service provider to use the services of other service
providers.
• Cell info display: Select On to set the phone to indicate
when it is used in a cellular network based on Micro Cellular
Network (MCN) technology and to activate the reception of
cell information.
