The modem ends up replying NO CARRIER at some point when trying the
connection the first time:

        [mm-at-serial-port.c:298] debug_log(): (ttyS1): <-- '<CR><LF>NO
        CARRIER<CR><LF>'

> 6 ) /etc/init.d/network-manager stop
> 7 ) kill modem-manager
> 8 ) start MM again: modem-manager --debug --log-level=DEBUG
> 9 ) start NM again: /etc/init.d/network-manager start
> 10) nmcli con up uuid baa2af1b-e21e-7bcf-f1ac-1a775c46ddc3
> 
> Now i have a working connection.

In the second try the modem didn't return NO CARRIER, connection
succeeded.

Is this something that you can reproduce always? I don't recall having
seen this situation myself when writing the Cinterion plugin.
