Is Tata Sky Binge+ set top box wothy at INR2499 upgrade as I just want OTT apps on my TV. Moreover, tata sky gives subscription to a few of those at INR 299 per month but they want the user to recharge for TV as well be it at their basic pack.
I will always recommend getting a fire stick and choose to pay for the apps you want. And you can use those services on your personal devices as well whereas Tata Sky's free subscription works only on TV.
After reading issues faced by people in IBF threads for Jio STB and Airtel Xstream devices with OTT subscriptions, I am also thinking FireTV stick is good option.
I have Hotstar, Eros Now and Discovery+Annual Subscription, and Zee5 and Sony Liv occasionally subscribed on FireTV OTT Apps, and it works fine.
