Reliance jio is now a days trending in all social websites because of the free unlimited 4g data for 90days i.e., for 3 months.
The speed will slow down after we use 4gb of data per day, so we can use 4gb data per day without any throttle after 4gb the speed will reduced for that day.
Not only we get unlimited data we also get free unlimited calls and sms with jio for 3 months.
We can do calls in jio only if our smartphone supports VO-LTE ( Voice Over LTE) .
If the smartphone doesn't support VO-LTE , we need to download jio join application from play store and make calls through this application.
