As We have seen in advertisements that you can enjoy 4g speed on 3g phones using JioFi But it is all false promises. I brought this so that my family could enjoy 4g speed in their 3g phones. I have 4g phone but my whole family could use 4g speed that will be better idea as the amount my family pay in a month is more then the plan they offered so I thought this plan is cheap for us.
I brought and start using it but faced problem from the very first day as range was only 10-15 feet only if you are sitting is same room then it connects your phone else it will be out of range if you are sitting in other room. somehow my family said lets just use it for a month from next month we will see something else but in between while using it disconnects automatically so if we doing something or playing game its very frustrating. I wont recommend this to anybody.
