When people are using free 4 g data or low cost data with a good speed you might be using Jio.
Jio have previously launched jiofi which was a buster in Indian market as those who can't afford high cost devices for them Jio wifi is the best, whether we talk about price 1999. it is, or speed it's very good.You can carry it along with you while travelling anywhere.
Jio wifi is the best with connectivity and has a memory card slot which allows a user to store and share data with the ease.
I am very happy using it and you should buy that.
Thanks to Jio for this device as who can't afford 4 g phones can use the device and use the wifi on their any other phones.3g ones.
