Your modem is using MBIM, not QMI, so you won't be able to use qmicli.
I don't know yet how to do the FCC auth thing in MBIM; maybe it's
possible through QMI embedded in MBIM but didn't really test that yet.
You could try to use usb_modeswitch to select USB configuration #1 in
the device, which should be QMI.
