Fwd: libqmi troubleshooting

[franco papalardo]

Hello

I'm working in mobile broadband for linux mini PC,

My issue here I don't know if it's hardware issue, SIM issue or there is
something that I'm not doing right now.

I have a Sierra AirPrime MC7710, also a SIM reader integrated in the
motherboard, the system is reading the SIM and also the 3G adapter, here is
some data:

qmicli -d /dev/cdc-wdm0 --wda-get-data-format

Those are a couple of outputs if you need something special let me know.
I can get my device to connect to the apn. The output is:

qmi-network /dev/cdc-wdm0 start
Loading profile...
    APN: surfo2
Starting network with 'qmicli -d /dev/cdc-wdm0 --wds-start-network=surfo2

I have been searching for like 2 weeks with no results

I appreciate if you can help me.
