Watcher has two options that affect your ability to obtain
GPRS, EDGE, UMTS, or HSDPA service in any given area. You
can select:
•
The frequency band you want to use
•
The network you want to use, if you are within the
coverage area of more than one network
Frequency band selection
Every GSM network operates on one set of frequency bands.
(See
“Frequency band selection” on page 35

modem is designed to change frequency bands automatically
as required to obtain network service. You can also change
frequency bands manually from the Network tab of the
Options window (
Tools > Options > Network
).
Note: Unless your service provider specifies otherwise, it is recom-
mended that you use the
Auto setting.
