Note: UnsolCOPS result confirms CDMA or
AMPS only mode, Permanent term is requested.
AT+COPS=3,0
Note: Ask for Analog only mode
OK
+COPS: 3,0
Note: UnsolCOPS result confirms Analog only
mode, Permanent term is requested.
Band Preference +WBND
Description:
The Band Preference of a CDMA modem governs the basic system acquisition behavior of the MS in
conjunction with the mode preference (+COPS) and the PRL (Preferring Roaming List). It’s important to note
that the PRL takes precedence over band preference when guiding the phone to a band. The PRL must
allow a particular band first, before the band preference can take effect. In other words, a band preference
change is simply a request; the PRL decides whether or not to allow it. If the setting is accepted by the MS,
the value will be written to non-volatile RAM and persist after a power-cycle.
