SELINT 2

AT#BND=
[<band>]

Set command selects the current band.

Parameter
<band>:
0 - GSM 900MHz + DCS 1800MHz
1 - GSM 900MHz + PCS 1900MHz; this value is not available if the ENS

functionality has been activated (see #ENS)

2 - GMS 850MHz + DCS 1800MHz (available only on quadri-band

modules); this value is not available if the ENS functionality has been
activated (see #ENS)

3 - GMS 850MHz + PCS 1900MHz (available only on quadri-band

modules)


Note: This setting is maintained even after power off.

Note: if the normal automatic band selection is enabled (AT#AUTOBND=1)
then the last #BND settings can automatically change at power-up; then you
can normally use the command.

Note: if the ‘four bands’ automatic band selection is enabled
(AT#AUTOBND=2) then you can issue AT#BND=<band> but it will have
no functional effect; nevertheless every following read command AT#BND?
will report that setting.

AT#BND?

Read command returns the current selected band in the format:

#BND: <band>

AT#BND=?

Test command returns the supported range of values of parameter <band>.

Note: the range of values differs between tri-band modules and quadri-band
modules
