Yes, you're right. It came from Bjørn Mork's patches who did this patch :

https://lists.ofono.org/pipermail/ofono/2013-February/014239.html

The "gobi" driver is plugged "manually" by ofono_modem_set_driver function

This card is mainly QMI but also have Diag, NMEA and AT interfaces
(ttyUSB). I think that's why he did it in setup_sierra.

OK, so I understand that Data feature is detected by scanning SIM
capabilities + chip capabilities (UMTS, LTE, ...)
Am I right ?

My SIM doesn't have PIN and I can use Standard QMI tools (libqmi) to
bring up a connection.
I will so investigate around SIM QMI requests / replies.
