My customer wants to know how to definitively determine which service is being used,
EVDO or 1xRTT, when the call is active.
After a data connection is set up, you can verify from looking at the output of the show cellular
connection command. The current call state would tell if it is a 1xRTT or EVDO (HDR) call.

My laptop is running an EVDO Rev A connection card with a signal of -92 dBm. Why
would the signal be so much worse with the 3G HWIC WWAN card: it is -125 dBm?
This reading (-125 dBm) means there is no signal, so the modem is not seeing the EVDO
service. Verify with the show cellular all command that the modem can see the EVDO signal.
Also verify that an antenna is connected to the main antenna input of the 3G HWIC.

What is the difference between the following two commands?
cellular 0/1/0 gsm band gsm-all-bands
cellular 0/1/0 gsm band auto-band
The gsm-all-bands command connects only to a 2G service (no wideband CDMA [WCDMA]).
The auto-band command is the default setting in the modem; with this configuration the
modem connects to 3G service if available.
