Today I was able to connect the MC 7304 via dualstack. 
(the huawei E398 did also work, just for reference)

It was a little bit tricky (crazy?), but it did work reproducable.

After switching in raw-mode - via side loading the ModemManager.
echo 1 > /sys/.... raw_ip
and 
qmicli -p -d /dev/cdc-wdm0 --device-open-net='net-raw-ip|net-no-qos-header' --
get-service-version-info

I made the connection via NetworkManager.

Ironically IPv6 worked better than IPv4. NM was setting addresses, routes and 
DNS for IPv6.

For IPv4 I had to do some things manually.

I have got all information - via different ways for IPv4 and IPv6. But in the 
end - raw ip is the/one solution for that device and maybe for some other.
