Hi, just want to update that the problem still exists under 19.10 live system.
I couldn't test whether the 77-mm-huawei-net-port-types.rules fix works,
since I only have a live-USB system where I can't add the file early enough.
How do we get the Modem Manager people to decide whether the above
Workarount badpractice works! Thank you!

Steffen Neumann,
Do you mind sharing step by step what you had to do? I'm on 17.10 and
have the same Huawei ME936, no matter what I did (including adding the
rule suggested by Philip Hufnagl) doesn't seem to fix the issue.
Windows 10 has absolutely no issues with it. It just works out of the
I can confirm that the workaround above by Philipp Hufnagl
indeed does the job. I am writing this comment from aboard a train ;-)
The connction setup is not very robust, and sometimes
fails at Simple connect state (4/8): Wait to get fully enabled
How to get a proper fix upstream now ?
Yours,
workaroud:
edit udev rule /lib/udev/rules.d/77-mm-huawei-configuration.rules
(create if not existent)
comment out everything in there
replace with:
ACTION=="add|change", SUBSYSTEM=="usb", \
ENV{DEVTYPE}=="usb_device", \
ATTR{idVendor}=="12d1", ATTR{idProduct}=="15bb", \
Status changed to 'Confirmed' because the bug affects multiple users.
** Changed in: modemmanager (Ubuntu)
Status: New => Confirmed

So mmcli will show me that the modem is alive,
but still the issue that I don't get an IP. Thoughts ?
