attached are the logs as described here: https://wiki.ubuntu.com/DebuggingModemmanager

the mm-test.py crashed though:

$ python ./mm-test.py
GSM modem
Driver: 'sierra'
Modem device: '/sys/devices/pci0000:00/0000:00:1d.2/usb7/7-1'
Data device: 'ttyUSB2'

    message, timeout)
dbus.exceptions.DBusException: org.freedesktop.ModemManager.Modem.General: The modem was removed or disabled.

after test script exits with an error I see that this

sudo killall modem-manager; sudo modem-manager --debug 2>&1 | tee /tmp/modem.log.txt

is still running. Then I try to connect to my mobile ISP and get the described above crash. And I see that this

sudo killall modem-manager; sudo modem-manager --debug 2>&1 | tee /tmp/modem.log.txt

is terminated.
