I am using it from last three months. the experience is good or better, according to me.
The speed and network are really great. better than my broadband. I am getting a download peed of 15+mbps and a upload speed of about 10 Mbps in the speedtest.net by ookla- the global broadband speed test.
Call quality is not better. SMS is getting delivered quickly. just like any other network, jio netword are good. and customer support service is also good.
