Hello friends, As u all know the reliance jio has launched the hotspot device.so mine is jiofi 3, based on the experience of 20 days I am writing this review. First of all I will let u know that the product I bought was of 1999rs plus the recharge amount of 309rs validity of 6months. The same jio sim which I was using in my phone was giving me worst speed but the same jio sim I tried in the jiofi device, I was just surprised by seeing such a huge difference.battery is also very good. And we can also do voice calling from the device by just downloading the jio4g voice.so it is an amazing experience no issue of device till now.one suggestion to all the buyers please buy from the brand store because if you buy these product in local area there they will give the same product in2500rs whrein we are getting the same product I 2300rs.so decision is your.thank you
