Cheap calling cards from US to India?

Calling Cards
akshay asked:


I recently moved to the US for my MS at UCLA. And like any other student on a tight budget, I am constantly on the lookout for cheaper ways of doing things. A friend told me about a new calling card she has been using – PCO4NRI. It has been recently launched and calls to India are as cheap as Re 1 for a minute! That really got me excited! Anybody on this forum has heard about this card?
