Table 21 - Operator status codes returned by 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:
set forceplmn=0|MCC,MNC| MCC,MNC,Network Type
For example:
set forceplmn=0
Sets the selection of operator and network type to automatic mode.
set forceplmn=505,3
Sets the operator to a manual selection made by the user where “505” is the Mobile Country Code for Australia and “3” is
the Mobile Network Code for Vodafone. As no network type (i.e. 3G or 2G) is specified, it is selected automatically.
set forceplmn=505,3,7
Sets the operator and network type to a manual selection made by the user where “505” is the Mobile Country Code for
Australia, “3” is the Mobile Network Code for Vodafone and “7” is the 3G network type.
