Tata Sky and Mozaic are two different things. Tata Sky is only the TV Channels Indian Origin and Mozaic is a complete package which includes TV, High Speed DSL and a Land Line, all three are pretty basic demand nowadays. For those who think Mozaic is not having sports channel for cricket they should subscribe to prime sports.
In the hot summer Tata Sky signal quality is pretty bad and you can’t fix it also technician will charge you for that.
