I am using jio wifi form 1month. I am experiencing a very good speed and purfomence. The bettry beckup is decent and very slim and portable to carry in pockyt. Charge up quickly.
Connect more then 10 device but not decrease data speed and better then other service providers like Airtel and has a calling feature too.
The jio welcome offer was extend to march 2017 so it is good for all purposes like offices and homes as well as. My father personally using this in his office and experience a good speed and perfomence then airtel.
