I wish to connect internet data card from MTNL 3G 'jadoo' with Ubuntu 12.10. How can I do it? I see a deb package but I am unable to use apt as the OS is not updated or apt has not been installed. Is there any other way round.

Now keep in mind that a deb package may not have all the needed dependencies. You can try to see if it works.
