- supported 4g modem ( L860 )
https://cgit.freebsd.org/src/tree/sys/dev/usb/serial/u3g.c#n197
Is it possible to use a 5G modem like the FM350-GL? If not, could you recommend another 5G modem?
The HUAWEI 3372 is a 5G USB, and is listed in the C code used for u3g driver in freeBSD 14.3
Which specific model of 3372 is TBD something to look into.
