Configuration
set gps-port
FortiWiFi-40F-3G4G (lte-modem) # set gps-port
gps-port Enter an integer value from <0> to <20> (default = <255>).
For the same reason as the set modem-port command, we have this set gps-port command. It is /dev/ttyusb1
by default. You can manually set the GPS port index with this command.
A GPS antenna is required to get GPS service. So this command has no effect on FortiGate
30E devices that have no GPS port and/or antenna.
set band-restrictions
band-restrictions Bitmaps for the allowed 3G and LTE bands.Ex:
0000000000000000-0000000000001008 (3G Mask-LTE Mask)
This command allows you to set the radio bands that modem can use for 3G and LTE service.
set image-preference

This command enables you to choose the corresponding modem firmware to pair with the inserted SIM card to be used.
Certain carriers, such as Verizon, may require special firmware. Otherwise, there could be no service. For carriers not
listed in the list, you can use the "generic" firmware instead.
Be sure to select the firmware image that matches your SIM card. The modem will not
connect if you set the incorrect firmware preference.
This setting is set to auto-sim by default. It enables FortiOS to automatically switch to the proper carrier modem
firmware based on the carrier information detected from the SIM card. When a new SIMîcard is inserted, the modem
firmware-switching will take place if the current modem firmware does not match that on the SIM card.
It may take up to five minutes for a modem firmware-switching operation to complete. During
this process, the modem could become unstable and may reboot itself for several times.
Hence, it is quite common to see the modem disconnected or undetected shortly after a new
SIM card is inserted, if auto-sim is selected.
