This may pertain to the FortiWifi 40C, however I' m not sure as we have the Fortigate 200D. But you may find this helpful.
To answer your question, there is a command that you can run from the CLI that shows all approved 3g/4g modems. It is ' fnsysctl cat /etc/modem_list.conf' Please note that I was advised to be careful running these fnsysctl commands by Fortinet Support. I' m not very strong with Linux but this appears to be a config file that might open up an editor of some sort. So just copy/paste to notepad to avoid and config file changes. This will show you a list of modem that are compatible with the Fortigate.
I was able to successfully get a 4g usb modem to connect with the following config in our 200D. This is working example with password and phone number scrubbed. Our provider is Verizon Wireless
config system modem
set status enable
set network-init " AT+CGDCONT=1,IP,vzwinternet"
set dial-on-demand enable
set phone1 " *99***3#"
set username1 " <PhoneNumber>@vzw3g.com"
set passwd1 <password>
set altmode disable
Everything above is exactly as it is in our Fortigate with exception of what is in the <>.
How do you find the " password" ? I' ve also enabled the dashboard widget and can see my modem shows Connected with Valid Service... but I don' t see any interfaces up..
I' ve also enabled usb-wan and wimax-4g-usb in config sys global.. but that may not be correct...
the widget showed my Verizon Pantech 290 as Connected and Valid service before putting your suggested changes into config sys modem and after.. so I' m missing something I think. btw.. I added all your settings accept for password because I' m not sure what it wants.. I can connect the USB modem to a laptop and using VZaccess connect without needing any PIN or password.
300E x3, 200D, 140D, 94D, 90D x2, 80D, 40C, handful of 60E's.. starting to loose track.
go to the CLI and run:
# diagnose fdsm modem-list
Also the following KB article lists some of the supported modems on FortiOS v4. At the end of the KB there' s some instruction about how to download the list of supported modems, not sure if it' s still relevant on the latest version, though.
Not at front of any of the devs, so can' t try, but good luck.

I am wondering if anyone can provide some advise?
I am looking at a 4G wireless backup option for our office internet.
We have a Fortinet FortiWifi 40C firewall, and this has a USB port that apparently a 4G USB modem can be plugged into (and used as a backup internet connection when our iinet goes down).
I ran this: fnsysctl cat /etc/modem_list.conf
And it displayed this:
Please be aware that this is not a 100 % guaranteed-to-work option. For testing, I'd get a prepaid SIM with some data volume and only after successfully using the 4G-wan port I'd buy a data SIM contract. For continued usage better avoid contracts based on data volume.
Usage is simple once you've got the 4G-wan port running: put the current wan port and the modem port into a "WAN load balancing port" (in v5.2) or configure ECMP on both, setting identical default routes but a lower priority on the modem port. This way, you can use the virtual port in policies regardless of the actually used wan port.
