JIO is just for those people who want free internet and calling. But nowadays JIO is not as good as before december.
Networks issues are getting poor day by day.
Sad thing is if u have two simcard support and u dont want to use Net on jio sim or u switch to 2nd sim for net then jio sim will be disabled. So that u can’t use phone calling service on jio.
And when u contact to customer care then you will get to know that they also dont know why is it happening.
Its a good product because its totally free till july 2017.
But what is the benefits if u are not getting fast or average speed.
In some places jio’s network is not working properly.
