I am using Tata Sky connection for six years , so I can say that tata sky is a good d2h service with good picture quality and feature.
But in this month I installed Tata Sky mobile TV becasue I wanted to watch news and IPL matches.
I installed the app and started to surf on Tv but that made me dispointed , when I searched Set max I was not available in the Live tv list . And its other live tv was very slow streaming so I could not explore other channel. Even when I was opening the that was hanging and taking too much time to open.
So I uninstalled this app from my phone .
I will suggest you if you want watch live tv just watch real tv in set top box and dont waste your time in app.
