It seems that both ModemManager and NetworkManager are doing the right
thing

[1493254626.0016] (ttyUSB2): modem state changed, 'enabling' --> 'registered'
(reason: user-requested)
If you're able to reproduce the issue, could you please enable debug logs in
both NetworkManager and ModemManager?
Please do the following (I know, it's a bit long, sorry for that)
$ sudo systemctl stop NetworkManager
$ sudo systemctl stop ModemManager
$ sudo NetworkManager --log-level=DEBUG --debug | tee $HOME/network-
manager.logs
then open a new shell and run:
$ sudo ModemManager -d | tee $HOME/modem-manager.logs
and then attach the two log file in your home directory
