More or less on-topic, I wrote a blogpost about this not long ago:

There is a 'qualcomm' GobiNet, in the CodeAurora project page, but
every vendor keeps its own. E.g. Sierra will modify the stock GobiNet
at least to add their specific VID/PID matches as well as their unique
USB interface layouts. I guess others do this as well. Sierra actually
also decided to port a fix that Bjørn did in the upstream qmi_wwan
driver, but don't know if others did that as well.

>From my POV, there are reasons to use GobiNet instead of qmi_wwan
(e.g. if you're looking for the vendor-provided product support), or
other things which we currently don't support yet (like firmware
loading)... apart from those, I'd really suggest to use qmi_wwan and
libqmi (with qmicli and/or ModemManager :) ).
