Yes, I believe it does. Or.. at least it confirms that something strange is going on. This part of the failed connection attempt after resume look very odd to me: ModemManager[1861]: <info> [1402484694.481304] [mm-iface-modem-simple.c:469] connection_step(): Simple connect state (4/8): Wait to get fully enabled ModemManager[1861]: <info> [1402484694.481349] [mm-iface-modem-simple.c:478] connection_step(): Simple connect state (5/8): Register ModemManager[1861]: <debug> [1402484694.481374] [mm-iface-modem-3gpp.c:395] mm_iface_modem_3gpp_register_in_network(): Launching automatic network registration...

Then we continue with a 'signal-state' indication (which is expected), followed by ModemManager concluding that the registration state is changed to 'idle' and failing due to that: ModemManager[1861]: [/dev/cdc-wdm1] Received message... >>>>>> RAW: >>>>>> length = 64 >>>>>> data = 07:00:00:80:40:00:00:00:00:00:00:00:01:00:00:00:00:00:00:00:A2:89:CC:33:BC:BB:8B:4F:B6:B0:13:3E:C2:AA:E6:DF:0B:00:00:00:14:00:00:00:12:00:00:00:63:00:00:00:05:00:00:00:02:00:00:00:FF:FF:FF:FF ModemManager[1861]: [/dev/cdc-wdm1] Received message (translated)... >>>>>> Header: >>>>>> length = 64 >>>>>> type = indicate-status (0x80000007) >>>>>> transaction = 0 >>>>>> Fragment header: >>>>>> total = 1 >>>>>> current = 0 >>>>>> Contents: >>>>>> service = 'basic-connect' (a289cc33-bcbb-8b4f-b6b0-133ec2aae6df) >>>>>> cid = 'signal-state' (0x0000000b) ModemManager[1861]: <debug> [1402484754.090164] [mm-broadband-modem-mbim.c:1771] device_notification_cb(): Received notification (service 'basic-connect', command 'signal-state') ModemManager[1861]: <debug> [1402484754.090172] [mm-broadband-modem-mbim.c:1524] basic_connect_notification_signal_state(): Signal state indication: 18 --> 58% ModemManager[1861]: <info> [1402484754.090224] [mm-iface-modem.c:1144] update_signal_quality(): Modem /org/freedesktop/ModemManager1/Modem/0: signal quality updated (58) ModemManager[1861]: <info> [1402484754.484416] [mm-iface-modem-3gpp.c:1167] update_registration_state(): Modem /org/freedesktop/ModemManager1/Modem/0: 3GPP Registration state changed (home -> idle) ModemManager[1861]: <info> [1402484754.484496] [mm-iface-modem-location.c:293] notify_3gpp_location_update(): Modem /org/freedesktop/ModemManager1/Modem/0: 3GPP location updated (MCC: '0', MNC: '0', Location area code: '0', Cell ID: '0') ModemManager[1861]: <debug> [1402484754.484540] [mm-bearer.c:261] modem_3gpp_registration_state_changed(): Bearer not allowed to connect, not registered in 3GPP network ModemManager[1861]: <info> [1402484754.484570] [mm-iface-modem.c:894] mm_iface_modem_update_access_technologies(): Modem /org/freedesktop/ModemManager1/Modem/0: access technology changed (umts, hsdpa, hsupa -> unknown) NetworkManager[1862]: <warn> (cdc-wdm1) failed to connect modem: Network timeout NetworkManager[1862]: <info> (cdc-wdm1): device state change: prepare -> failed (reason 'gsm-registration-timeout') [40 120 32] NetworkManager[1862]: <info> NetworkManager state is now DISCONNECTED NetworkManager[1862]: <debug> [1402484754.485784] [nm-manager.c:4165] policy_activating_device_changed(): ActivatingConnection now (none) NetworkManager[1862]: <warn> Activation (cdc-wdm1) failed for connection 'FONIC Vorgabe' NetworkManager[1862]: <debug> [1402484754.485885] [nm-device.c:5261] nm_device_queue_state(): (cdc-wdm1): queued state change to disconnected (id 431) NetworkManager[1862]: <debug> [1402484754.486259] [nm-device.c:5219] queued_set_state(): (cdc-wdm1): running queued state change to disconnected (id 431) NetworkManager[1862]: <info> (cdc-wdm1): device state change: failed -> disconnected (reason 'none') [120 30 0] NetworkManager[1862]: <info> (cdc-wdm1): deactivating device (reason 'none') [0] NetworkManager[1862]: <debug> [1402484754.486360] [nm-firewall-manager.c:166] nm_firewall_manager_remove_from_zone(): (cdc-wdm1) firewall zone remove skipped (not running) NetworkManager[1862]: <debug> [1402484754.486649] [nm-dns-manager.c:995] nm_dns_manager_begin_updates(): (update_routing_and_dns): queueing DNS updates (1) NetworkManager[1862]: <debug> [1402484754.486718] [nm-dns-manager.c:1013] nm_dns_manager_end_updates(): (nm_dns_manager_end_updates): DNS configuration did not change NetworkManager[1862]: <debug> [1402484754.486745] [nm-dns-manager.c:1017] nm_dns_manager_end_updates(): (update_routing_and_dns): no DNS changes to commit (0) But there are no MBIM messages explaining why MM sets the state to 'idle'. Is this because of the missing reply, Alexander? Why don't we just trust the (more current) result from the indication? We do know that the modem is registered to the home network here, or?
