Hi Aleksander.
I've had the same problem since I updated my Huawei E220 to firmware revision 11.117.10.02.00 and 11.313.02.00.01 as detailed in duplicate bug #932824 <https://bugs.launchpad.net/ubuntu/+source/modemmanager/+bug/932824/>. Before firmware update (possibly with firmware 11.110.xx?) everything was working fine.
I can confirm that the "ports" branch works for me. Debug log of successful connection is attached.
