I have been using Jio Sim since August 2016, The internet service is very good . both in terms of connectivity and speed. however the voice call service needs lot of improvement and making people live on the internet.Making Internet accessible to everyone at rates which are really affordable Plus making other telecom operators reviews their own plans and service . For me Jio is doing what its name means so I’m happy with it and will continue using it. But only things Jio is little backward is in its calls and must also introduce an in built call recorder for its Jio 4G voice app.
