I bought my jiofi-3 device for 1999 rs and its been a month. This device is super awesome, as it gives very high speed internet fair quality calls and an access to the jio network which has been a heartly wish of the people with 3g smartphones. It looks very sleak from the outside as it has a matte finish and the company has also made some changes from the last model jiofi-2. The battery is increased to 2700mah, the appearance has been changed, and an additional wps button. I'm totally satisfied with this jiofi-3 device. Got it in an offer where I got additional 4 months free internet and calling with a daily high speed quota of 2gb.
I recommend to buy this device as soon as you can
