Tata Sky is very good DTH operator in india. I am using it from last 3 years .Picture quality is excellent no doubt excellent sound quality.but not satisfied it’s service because he charged evry time visit, once it’s shows three times bad signal, I was call to customer care and three times take service charge, that’s not good if he provided service then service should be free as such as airtel it’s very helpful for us.Except service it’s useful and good thing is that if you are not available in your home approx 1 month, you can recharge after one month . If he will provide free service then it is valuable for us.
