And if you are going to be all over India, don't get into hassels and just pick BSNL.
While it is certainly true that BSNL has the widest coverage, their networks are oversubscribed. What that means is there will be times when it is impossible for others to get through to you and for you to call. That made it very unreliable for me - I switched to Airtel and it works fine. Occassionally, if you dont have cell phone coverage and need to make a call from a rural area, head to the nearest PCO. Good luck!
