Hey,
Everything has always worked just fine and also after swtiching to linux-lts (3.10.25-1-lts ) everything worked like it should.
But after unknown reason modem doesn't work now. Biggest change I've made is uninstallation of linux-headers package, installation of linux-lts-headers and building of vboxdrv with dkms.
Lets begin with dmesg:
dmesg

Kinda solved.
Reinstalled system completely but problem appeared later.
Booted into Arch installation and connected using wvdial to internet and was ready to reinstall but then wanted to try one more time if it would work.
So after exiting installation and logging back to system I was able to see ttyUSB[0-3].
Problem continues to appear but I solve it everytime by booting to Arch installation and by connecting in installation environment once and booting back to main system.
Guess problem is with modules or modeswitch. Don't have knowledge to solve tho.

I'm having similar problems with ZTE MF667 which worked flawlessly in the past. Can you post output from
systemctl status ModemManagerbecause mine looks weird.

I don't use any networkmanager.
But what you can try is to disable zeroCD with minicom, can't find instructions but didn't work for my modem.
In your case I think problem isn't with wrong mode but rather that current version of modemmanager doesn't support your device yet.
/var/cache/pacman/pkg has old packages, try to install older package of modemmanager.
