The average quota is 1.5GB/day (for the latest recharge, they provided 3gb/day). That's a lot !
Some side effects of Jio have been : 1. average media consumption per user, specifically video(youtube, netflix, amazon prime) has gone up drastically 2. voip calls(audio & video calls on whatsapp, telegram) have gone up drastically ! 3. A lot of users, especially youngsters i know, dont download content anymore, they stream it ! Its an interesting usage behaviour shift !
I think Jio's end game is content - getting Indian users to pay for content will be tricky though !(there have been very few successes - unlike the us, the average indian user doesnt like paying for digital subscription content , paid tech news and analysis site, https://the-ken.com/ is an exception)
