I will share my user experience of JIO FI 3 .lets get started.
I personally not enjoying services of the same .i will tell you some of the points which you also don"t like if you use it
Speed:There are option of connecting 31 devices at once but if you connect only two devices at once and start downloading anything from any on e of the devices then u wont be able to surf anything on the other device.U can check this out if u found it wrong.I don"t understand if issue comes with two devices only then how it comes with 31 devices support?
Connection Reliability: Its also an issue because it will start refreshing network once in a while and it will get disconnected.
Service and Support:I called to the customer care and also visited service centre but they don"t have the answer for these issues.
Final words : Don"t get one until you check it over the counter.
