which phone company?

Hei Ami In India BSNL or airtel is the Best . I always use BSNL . But BSNL sim cards are not often available in markets.

 

Both have their own pros and cons.
BSNL has lesser problems with false/ extra billing, where Airtel has a good customer support. So find out from people around in tht area and use.
But u are talking for a short period. Airtel has good coverage if you ll be traveeling around in India and should suit for a matter of month or two. I hope you know, it s those pre paid cards you should be going for.
