Configure manual carrier selection
By default, your TX54 automatically selects the most appropriate cellular carrier based on the
SIM that is in use and the status of available carriers in your area.
Alternately, you can configure the devices to manually select the carrier, based on the Network PLMN
ID. You can also configure the device to use manual carrier selection and fall back to automatic carrier
selection if connecting to the manually-configured carrier fails.
You can use also use the modem scan command at the command line to scan for available carriers
and determine their PLMN ID.
