Looks quite good in the log, but could you post the part of "lsusb -v" for the unit? I'm wondering if it is missing a network interface, as it tries to dial using "*99#".

Would you please be able to test if this problem also apply to the latest development version of Ubuntu by testing a daily live CD?: http://cdimage.ubuntu.com/daily-live/current/

I see that it contains a newer version of modemmanager (1.4), which might have solved the problem.

No luck. Booted from a live vivid pendrive (iso md5sum: 40493fb5d594606908dcda45624161f7). Added a new broadband connection and tried to start it. No internet.
The old modem works (log attached), but the new does not.

I have tried to use that page, but was not helpful (nor especially clear).

In *my* lsusb there is no 14fe id, nor 157c id. In my syslog there is a line stating that usb_modeswitch *did* switched the modem - without any udevrules-patching. ("usb_modeswitch: switched to 12d1:1506 on 1/3") (Was it an incorrect switching?..)

That I cannot interpret well: "the connection will appear in your panel as it would if you would insert an ethernet cable". I never insert ethernet cables, I have solely the mobile net, in the panel nothing appeared.
What I did was: in Network Connections, Add, Mobile Broadband, then either appeared there (in the combo) a "Huawei Broadband device" or such (I have no screenshot), or not - did not seem to matter. In either way, my old modem worked. And the new did not. I selected Hungary, Telenor, "mobilinternet" plan, and disabled roaming (and left all others at the default).
Was this method wrong? What would be the appropriate method to set up (add) this modem in network manager?

"See the usb_modeswitc_data package for details. [] You may update it" - I have tried to temporarily use my old modem (connect to the network), issue an apt-get update and apt-get install usb_modeswitch_data, but there was no such package, could not search for it, failed.

Okay, I think we can take this bug upstream as it probably is not cause by something Ubuntu has modified.

To complete this bug report, please run "apport-collect 1404068" in a terminal.

From the logs, it seems like there is some issue detecting/configuring the network interface of the modem.

There is no network interface in the lsusb listing provided by the reporter, there are 3 serial interfaces:

if#0 utps_modem
if#1 utps_pcui
if#2 utps_diag

A 12d1:1506 without any kind of net interface is unusual for a Huawei LTE device and also remarkable since idProduct in the lsusb listing describes the device as a "Modem/Networkcard".
The 3rd digit in 4 digit Huawei product numbers denotes the speed where 7 indicates CAT4.
There is no way Huawei would produce a LTE CAT4 device with only ppp modem dialup so I'd say that this dongle has been tampered with, the net interface has been disabled via AT SETPORT cmds.

@shoohuy (eyygsqvcbzugaxzpa), as indicated in comment #12, did you do anything special with the configuration or firmware of the device? Do you know if it works with other operating systems, like Windows or Mac OS?
