I installed Ubuntu 12.10 on 2 disk partitions and installed MTS MBlaze usb modem on both the partitions.
When I start any of these 2 partitions, I get the message "Connection Established", but "Modem Manager crash" message in both of them, and I can't open any web page, nor ping
MTS is working fine in Ubuntu 12.04 partition.

Is this Ubuntu 12.10 bug, or something particular with the new version?

I manually downloaded wvdial and its dependencies, installed and finally it is running.
Thanks to all of you for support.

The method originally aims Ubuntu 12.04 but a previous AskUbuntu post says this method works with Ubuntu 12.10:

Mobile Broadband not working in 12.10
