Guys,
As a student from India to USA, I know how hard it is to manage your limited pocket. Personally I have spent lots of money on calls to India and realized that I need to do something with this!
I started up a blog
http://sam-freecalls.blogspot.com/
where we can find the ways to call home. I found pretty many websites which can offer us free calls using a cell or landline phone.
My parents have no PC at home, thus I can not call them using skype or yahoo ms. So feel free join our community and get benefits from it.
