Network scan and manual network selection by SMS
Performing a network scan
The get plmnscan SMS command enables you to perform a scan of the cellular networks available at the time of the scan.
It returns the following semi-colon separated information for each network in range:
MCC
MNC
Network Type (LTE, 3G, 2G)
Provider's Name
Operator Status (available, forbidden, current)
The following is an example of a response from the get plmnscan SMS command:

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.
• If the connection status is Waiting and connection mode is Connect on demand, the get plmnscan SMS will change the
connection status to Down, perform the scan, send the result through SMS and then restore the connection status to the
Waiting state.
• If the connection status is Up and connection mode is Connect on demand, the get plmnscan SMS will cause the
connection to disconnect, perform the scan, send the result through SMS, and then restore the connection status to the
Waiting state unless there is a traffic which triggers a connection in which case the connection status will be set to Up.
Setting the router to connect to a network
The router can be instructed by SMS to connect to one of the networks returned by the get plmnscan command. The set forceplmn
command forces the router to connect to a specified operator network (if available) while the get forceplmn command retrieves the
currently configured network on the router.
Command format:
