Six months ago I purchase jiofi 4 Wi-Fi from Reliance store and I am using this from last six month it’s my personal experience that the speed of the jiofi is good then other dongles and models I found that the speed of this Wi-Fi router is so good that you can do your work without any problem and obstacle you have to recharge with the best plan of jio or the plan which you like and you will get uninterrupted service from jio as well as NET and calling facility and message to other mobile numbers and to your number so if someone wants to use internet service I must recommend him or her to take jiofi 4 Wi-Fi router.
