Jio tv a unique platform for only jio subscribers. You install this app then choose from categories the channels you want to watch and then click on that channel, Voila! Magic you can see live tv on your phone.
Now-a-days every channel does live streaming of their live channel on their site. This app gets feeds from there and show it to you on the go and waste your data, then your allowance gets over then you get a message to recharge minimum with 51rs to get 1gb data and many people do it, so its a gimmick to waste your allowances.
For company its their bread and butter. They will go to any extent to exhaust your data by giving you multiple options and making money out of you. If you are so big fan of tv toh ghar pe tv dekho na.
