Jiofi is a nice product but its too expensive . It costs Rs.2000 A middle class man cant afford it. The Internet speed of the Jio network is very low it is around 2 Mbps only and the connection is quite reliable But the battery life of the device is not nice . Under the jio offer customers also get a jio sim, a jiofi device and a plan also . The good thing about the jiofi is that phones that do not support 4g also get advantage of 4g through WiFi. My personal opinion is that insted of buying jiofi buy jio sim and enjoy 4g network.
