Reliance jio is a great network, I am using this sim scince from 5 months and there is not any single iasue regarding any network problem, So I find it a great sim. Moreover reliance jio is giving us free calls, sms, data which is awesome. I really thanks to reliance jio for giving us this free data. But from 1st April, 2017 there will be no free usage, but reliance jio has a great tarrif plans, so I have taken jio prime mebership for the benifits.
