Hi Aleksander,I hope that this is the relevant fragment. Caught it's not easy, verbosity is too detailed.

Hoola Diego,I’m dealing with a Sierra Wireless MC7354. I’m testing it on coverage limits (removing antenna) on UTMS. In normal operation, RRC_STATE moves between CELL_DCH, CELL_FACH and CONNECTING while ModemManager.Modem.state keeps CONNECTED. Sometimes the modem reach DISCONNECTED state in spite of the fact that ModemManager.Modem.state keeps CONNECTED too. In this state, Modem doesn’t reconnect anymore until I make disable/enable call.
