I’ve been on Jio Fiber for about 6 months now.
Our setup:
The drawing room has the "box" ( ONT) & a landline phone linked to it. This box is connected to fiber optic cable which enters the premises. From that box I have placed a LAN RJ45 cable to the next room and connected a modem / router as repeater. This repeater in turn is connected to a LAN RJ45 of about 30 feet to another router at the other end of the apartment. This works better than a WiFi range extender, though with ugly wires visible.
Pros:
This is true FTTP ( Fiber to the Premises) / FTTH ( Fiber to the home) and not FTTC ( Fiber to the cabinet which terminates at a cabinet on the road with last mile being CAT5 cable or copper)
Stable in terms of speed and latency
I am still on the free plan because I paid Rs4500 for the dual band router
No buffering for video streaming applications
Unlimited landline calls bundled
You can use JioCall app from your mobile/tablet ( must be connected to the Wifi) and make calls using the landline number
All OTT apps ( movies, music, TV etc) are bundled
Dual band router supports 5GHz and can connect up to 40 devices
Cons:
Many websites including torrents are blocked
Local cable operators cut the overground cables to stop people opting for GigaFiber. For us this happened once in the evening and was fixed next morning
Be aware that everything we browse is being used for data mining, though every ISP does this. Buy a VPN subscription ( not yet done by me) to have a pretension of privacy.
Overall I’m happy and would certainly recommend this. You can keep both your existing connection and this for a month, just in case you want to go back to your old operator. That’s what I did with Airtel V Fiber and Jio GigaFiber before switching over.
