I am ADTV HD (Multi TV) customer since 6 years. My ADTV validity expires October Ist week. I am planning to go for TataSky, mainly for quick HD addition (ADTV not added KTV HD yet). My current plan is Rs 429 (South Max HD with Tamil) Can any one in TS explain, how much will it cost per month to subscribe all HDs + Tamil regional Channels? What is the Child connection subscription per month? How many child connection one can have?
