Network.
To select the network mode, select Network mode and Dual
mode, UMTS, or GSM. In dual mode, the device switches
automatically between networks.
Tip: Selecting UMTS enables faster data transfer, but
may increase the demand on battery power and reduce
the battery life. In regions close to both GSM and UMTS
networks, selecting Dual mode may cause constant
jumping between the two networks, which also
increases the demand on battery power.
To select the operator, select Operator selection and
Manual to select from available networks, or Automatic to
set the device to select the network automatically.
To set the device to indicate when it is used in a microcellular
network (MCN), select Cell info display > On.
