Your modem does expose several tty ports, but only one replies correctly
to our AT or QCDM probings; which means that you end up with one modem
which only has 1 port usable, and which also means that you end up not
being able to refresh signal quality while connected.

But your modem (VID 0x19D2 PID 0xFFF1) is Qualcomm-based, so there's a
chance that it is a QMI-capable modem (and therefore manageable via the
QMI support in ModemManager >= 0.7.x); but I didn't see it listed in the
qmi-wwan kernel driver, so cannot really tell; you would need to check
that yourself by adding the VID/PID pair to the kernel driver and
recompiling it. Modems managed via QMI are able to update signal quality
while being connected.

Bjørn, Dan, have you seen this ZTE-branded CDMA device before? Gobi1k maybe?
