[QUOTE=SQ421;16168967]If your trips to India are semi-regular (like mine are) it might be best to get a post-paid SIM card. IIRC a few years ago, MTNL/BSNL as well as AirTel and Vodafone had a "no monthly rental, lifetime validation" scheme for postpaid accounts.

I am now on my third "lifetime" SIM as each time I dissapear for a couple of months the number gets reallocated!!!
Airtel, Aircel, and now Vodaphone, let's hope this one is ACTUALLY lifetime.
