I have been using my internet service by jio since 8 months and had got a clear idea that one cant refuse to attain service from it.
Ya, it covers almost all part of india and running smoothly all over them
I used to get around 2mbps earlier but now it gives only 50kbps which is really dissatisfying
But its costumer care service is not only good but also covers almost our every request
It have extented its service and thus I found it really useful.
