Dish TV is the oldest DTH service provider in India. So they have experience. I researched and found that Dish TV has some freedom about HD channels and they are cheaper and I liked it. Tata Sky is really restricted and costly. About other operators I live in Central India so Sun Direct is not for me. Independent TV is in bad condition and less HD channels. Videocon has been merged with Dish TV. So that's like two sides of the same coin. So truely there is only one left that is ADTV. I personally don't like Airtel for how they charged us for our phone bills in past. So I opted for Dish TV.
