available band)
Example:
You can set the modem to use multiple bands using a bitwise OR. For example, to set
the modem to use the GSM850 and GSM900 bands, you would issue the command
AT!GBAND=00080300:
0000000000080000 (GSM850)
0000000000000300 (GSM900)

0000000000080300
Note: It is not possible to perform handoffs to bands not in the currently selected band
mask.
Note: Due to stack implementation, the query form of the command (!GBAND?) reports
WCDMA800 for both WCDMA800 and WCDMA850.
