Yes! JioFi is the device I was looking for since jio launched . As we know jio is only works on 4g phone but jioFi allows you to work jio on 2h and 3g phone through hotspot .
I got some issues innitially relating to speed but later on hio care resolve my issue with in few time . The service they provide is great.
As we know this too that jio HAPPY NEW YEAR OFFER about to eng on 31st March 2017 so guys hurry! If u want to use jio sim or jiofi then get the jio member ship as soon u can before 31st march . After 31st March you wont be able to use jio internet .
Overall it is a great device . And I am fully satisfied with jiofi .
Thank You .
