Few days back I received some prank calls from some unknown mobile numbers. And since then, I was in search of some directory services of Indian mobile numbers. And guess what? Few days ago, I stumbled over a website which claims that it can provide service area details of any Indian mobile numbers.
This service provided by InformationMaddness and BharatiyaMobile has a database of all mobile operators and its numbers that are operational in India, I would prefer the former one as it gets updated regularly with latest numbers. So, you too may check out the service area details of any Indian mobile number.
