5: Data Connections Through
GSM and GPRS
• Dial-Up Circuit Mode
Calls
• Packet Mode
Connections
Note: You cannot have a data
and a voice connection at the
same time. If you have a data
connection when an incoming
call occurs, your caller will get a
busy signal or be put through to
your voice mail box.
Note: Depending on your billing
plan, there may be a surcharge
or different billing arrangement
for GPRS packet mode connec-
tions.
Note: Although you may not be
charged extra money while
connected in packet mode, but
not actively moving data, the
AirCard network card continues
to use power in that mode. For
best power conservation from
your computer, shut down any
AirCard wireless connections if
you do not need them.
