No doubt tata sky is one of the best and popular dth service in india but as I experienced in last 1 year , it is expensive to use.Normal packs are too expensive. In normal pack you have to pay 60/month for sports channel.No problem with picture and sound quality in general days but in rainy days there is signal problem with it.Customer service is not bad but they charge a lot for simple services.This year I am going to change my dth because I think I can use better service in same price using other dth.
