Please refer to the original bug report if more details are needed.

After resuming from a suspend, the MBIM-managed Sierra Wireless EM7305 doesn't seem to properly allow connections if ModemManager had an open MBIM session during the suspension. After resuming, a connection attempt will make the device connected, but not working properly.

   [1404835174.470611] (wwp0s20u6c2i12): port now connected
   [1404835174.470684] Connected bearer '/org/freedesktop/ModemManager1/Bearer/0'
   [1404835174.471132] Modem /org/freedesktop/ModemManager1/Modem/0: state changed (connecting -> connected)
   [1404835174.471737] Simple connect state (8/8): All done
(now something happens, and it seems we get a Disconnection via DBus?)
   [1404835181.411298] Disconnecting bearer '/org/freedesktop/ModemManager1/Bearer/0'
   [1404835181.412289] Modem /org/freedesktop/ModemManager1/Modem/0: state changed (connected -> disconnecting)
   [1404835181.412634] Launching disconnection on data port (net/wwp0s20u6c2i12)

Would be good to get a set of ModemManager *and* NetworkManager debug logs of the same run.
