Micromax 3G usb modem on ubuntu 12.04

I am using Micromax 3G USB modem to access Internet for long time, and it was working fine with previous distribution of Ubuntu. I have recently upgraded my operating system from Ubuntu 11.10 to 12.04. After upgrading I have seen that system is not detecting my Micromax modem. Fortunately I found a very simple solution and here I am sharing it.
You have to just edit the /etc/modules file. Use this code

$ sudo gedit /etc/modules

and then add this two line at the end of the file

usbserial
option

This has worked for me. Hope this will also solve your problem.

NB: If you are using Ubuntu 12.10 probably the above method is not working. Check this post for work around.
