Notes about the network connection status when using the get plmnscan command:
If the connection status is Up and connection mode is Always on, the get plmnscan SMS will cause the connection to
disconnect, perform the scan, send the result through SMS and then bring the connection back up again. If the
connection status is Down, the router will perform the PLMN scan, send the result and keep the connection status down.
