I'll try with that firmware, thanks for the link. I'll first need to
find a Windows machine...

Yeah, maybe it's an issue in how MM treats the 'disabled' state, as it
would map to low-power mode when possible. We could always try to remove
that association and treat the low-power mode as an additional feature
with its own DBus method to enable/disable (which would work only when
the modem is in 'disabled' state). That would definitely hide most of
the issues behind an explicit user action.
