AT over MBIM is possible, but we decided not to implement it.
The big advantage of MBIM is a ready-made driver on Windows and on
MM/ofono. Adding AT over it would mean reworking the driver, so no
more advantages.
Over QMI I don't know.
QMI over MBIM is also possible, but with the same disadvantage as AT over MBIM.
