My experiance on reliance jiofi is best I bought it for only rs 1500 itis very cheap the battery backup of reliance jiofi is best beacause I can use it regularly uptp 4 to 5 hours daily internet speed is very nice beacause we can download videos at 150mbps speed and main thing of joifi is we can connect 4 to 5 smartphones at a time me and my group enjoy this jiofi it is very small dvice I can put it in my pocket and go anywhere like colllge and gardens I have 4g smartphone and my frind have 3g but he also can enjoy 4g enternet on this device overal reliance 4g is the best device.
