It works fine with wvdial, because wvdial is using PPP. This device is
an Icera-based ZTE modem with an emulated ethernet port, which provides
much higher speeds than PPP can. Unfortunately, we need to handle these
devices specially via some udev rules, like the K3805z, and it requires
the latest version of ModemManager (either 0.6.0, or 0.5.4).
I'm not yet comfortable making the change upstream to have this modem
use DHCP instead of static addressing, because when I added support for
the
MF691 (T-Mobile Rocket 2) long ago, I verified it was working with
static IP addressing. I'd like to figure out what changed between that
version and the generic version, perhaps a firmware update or something.
In any case, the real fix here involves changes to both NM and
ModemManager, but for the time being you can make things work if you
have the latest ModemManager by modifying
the /lib/udev/rules.d/77-mm-zte-port-types.rules file and adding your
device near the bottom in a line like:
ATTRS{idProduct}=="1203", ENV{ID_MM_ZTE_ICERA_DHCP}="1"
