Thanks; 0.7.x and ModemManager have been updated for your device and a
few others that I could find .INF files for.  Can you give those a shot?
In your case, grab this file and put it into /lib/udev/rules.d/:

http://cgit.freedesktop.org/ModemManager/ModemManager/plain/plugins/77-mm-zte-port-types.rules

Then unplug and replug the device and lets see where we get to.
