Comment 4 Aleksander Morgado 2014-03-10 19:11:57 UTC 
Does this still happen? ModemManager just gets a NO CARRIER error; notifying of the network disconnection.

Would be worth trying with MM 1.x built with QMI support, as this seems to be a QMI-capable device.
Comment 5 Igor Gnatenko 2014-03-10 19:24:22 UTC 
Unfortunately I can't reproduce, because don't have this modem at this time.
Comment 6 Aleksander Morgado 2014-03-10 19:28:30 UTC 
I'm going to close it as obsolete. For the looks of it, could very well be a random issue in the network... If you can ever repro it with MM 1.x; please reopen. Thanks!
