I am using reliance jio wi-fi for past few months very high speed router. with this help us to 4G speed internet in our 3G mobile and computer and laptop also. this network search power is nice, even if the signals is low but net speed gets good speed. its battery life is a bit less and heating .the problem is find out in jio service centre when there is problem in it . According to me jio fi is a super speed for usage and very useful for value of money .
