Tata Sky is on of the precious DTH operator in India in compare of other operator. It charges only high amount monthly rental without providing all channel. If you want all channel then you have to pay around rs.300/months excluding HD channel.
If you want your HD channel then you have to pay extra around rs.200/month. It is so expensive or we can say that it not available easily for common family.If we compare others operators like Videocon and Dish Tv then these are lower in Monthly rental.
