Thanks for sharing that thread (not sure why I didn’t find it when searching originally).

Unfortunately, I’m still not having any luck. This etc/config/network entry works great, but only at 3g:

config interface 'modem'
        option country 'country73'
        option sp 'isp3'
        option service 'umts'
        option dialnum '*99#'
        option apn 'epc.tmobile.com'
        option username 'none'
        option password 'none'
        option metric '40'
        option proto '3g'
        option ifname '3g-modem'
        option device '/dev/ttyUSB0'

But as soon as I change option proto from ‘3g’ to ‘ncm’ to try to achieve a 4g connection, nothing else seems to work. I’ve tried specifying option device ‘/dev/ttyUSB0’, ‘/dev/ttyUSB1’, ‘/dev/ttyUSB2’, and ‘/dev/cdc-wdm0’. None makes a connection. Same true when I try to use option proto ‘qmi’. Nothing connecting.
