[ubuntu-in] How to setup ZTE AC8700 EVDO on Ubuntu

[Ramnarayan.K]

Hi

Just laid my hands on a 3G ! ZTE AC8700 EVDO data card from BSNL.

I thought it would be simple to setup and run but ran into snags.

Checked the net but there are bug reports but no real nice how to's

The resources available are from BSNL (surprise surprise) but not good enough

 and from

I tried the following
1. Inserted the device and this is the dmesg (snipped to relevant sections only)

[   76.817632] usbserial: USB Serial Driver core
[   76.834853] usbserial: USB Serial support registered for GSM modem (1-port)

[   76.840143] usbcore: registered new interface driver option
[   76.840147] option: USB Driver for GSM modems: v0.7.2

Here the question is why is it showing up as a GSm modem ??
