I received my Android tab today and it doesn't have inbuilt 3G data. I have a 3G modem (ZTE MF 180) and it didn't work when I connect it. It's a chinese tab and supported-list doesn't contain my modem model. But I think Android should be able to take the device as a generic modem and communicate with my data carrier. I don't need fancy stuff like SMS or phonebook - just like the modem support on Ubuntu.
I'm just few hours old in Android world so any help is greatly appreciated.
