Comment 5 for bug 1244775

UPDATE: I stand corrected. This E1690 modem is not "mode-switched" the FIRST time connected to the machine. Watching lsusb, the device just stays at its original ID of 12d1:1446 and never switches to 12d1:1001.

But if I unplug it and replug it, the 2nd, 3rd, 4th, times it is always correctly switched to 12d1:1001 and then "Mobile Broadband" is displayed in the Network Manager. It is only this "first time" it sits a 12d1:1446 and is not switched.

Maybe this is the same situation as the original poster, ivano, was seeing.
