Hi,

It's been a while since I played around with LTE USB sticks but I have a 
vauge memory of some kind of race condidion between (default) kernel 
modules and modem interfaces which by the way may no longer be valid.

Anyhow, looking at my notes... (KERNCONF)

device          ucom
device          u3g
device          uether
device          cdce

Since these are notes from an ARM SBC these lines are also present in 
/boot/loader.conf not sure if they (umodem) are related or not

# Configure USB OTG; see usb_template(4).
hw.usb.template=3
umodem_load="YES"

...and 
https://forums.freebsd.org/threads/4g-usb-modem.67263/page-2#post-431369

This will only work if your modem offers a CDC ECM/NCM interface and not 
PPP which makes your experience a lot less painful ;-)

Best regards,
Daniel
