Comment 5 for bug 796871

Could you please follow the steps here: https://wiki.ubuntu.com/DebuggingModemmanager under Getting Debug logs to get the current debugging logs from MM while reproducing the issue?

Also, I suspect this may need to load the correct special firmware with gobi_loader if it's not already being done. I think the debug logs will say whether it's the case those (we should see from the return codes from the modem)
