Try the following patch if you can; also ensure you are building
ModemManager with QMI support (which is the default). Basically, we've
never seen a QMI SimTech device before, and the SimTech plugin is only
built to work with PPP-style devices. So it may work but just not use
the wwan0 port. This patch will move your device to the generic QMI
plugin:
