Jio is no longer onboarding new prepaid connections bro. Only postpaid connections are given now for both Fiber and AirFiber.
Because both type connection accounts (prepaid and postpaid) still exist, they have showcased it on their website.
Answering your question, prepaid connections used to have Rs. 1500 charges for internet-only connection and Rs. 2500 for internet+STB connection. This cost included refundable security deposit of Rs. 500 and Rs. 1000 respectively that you can get back refunded after connection cancelation.
Postpaid connections have no security deposit, no device charges and no installation charges. Similarly, no device or security is refunded after connection cancelation.
One month pack was only available during prepaid connections.
When I took JioFiber prepaid connection a few years ago, they even gave 2 months free 150 Mbps plan worth Rs. 999 using some kind of offer where I needed to pay only on second month and first and third month were free.
I think some of our forum members also availed the same offer. Those good days are over now.
Congrats Bapun bhai.
1. You should check their ping. That always seem to be high and it will cause problem in watching OTT(Happened with me as you can see. I posted in that jio thread).
2. About that free plan, it's free for 3rd month. It's like 1st month is free. For 2nd month, you have to recharge. Then only you can use that voucher on 3rd month.
