The set command sets locked bands and bitmasks to limit supported bands.
Supported bands are masked with permanent and runtime
masks. A logical AND
operation is performed to
%XBANDLOCK commands. If a permanent or runtime mask has been given, it
is required that the second mask has at least one band in common with the first mask.
Otherwise, the command returns ERROR. The command returns
ERROR at an attempt to disable all supported
bands.
Permanent mask is stored to Non-volatile Memory (NVM) approximately
every 48 hours and when the modem is powered off with the +CFUN=0
command.
%XBANDLOCK=<operation>[,<band_mask>]
