I have used Airtel Digitel TV since last 5 years that is a good picture quality and good signal strength and clear and quality sound. Airtel digital tv is a High Price recharge other than digital tv but signal quality and voice are great so I gives 3.5 stars for Picture quality And 3.7 star for sound quality.
There RE SOME problums in airtel digital tv the recharge is very costly other than the other digital tv
