I m using jio sim from the launch of he jio sim. I even took all its benefits of free daily internet and unlimited phone calls. I liked it the most. And jio made an huge change in market. Other networks like idea, Airtel, vodafone, were giving internet services in the prices of gold anccording to me. But when jio launced it shaked them all and made them to give internet services very cheaply. But even after giving cheap services they were not near jio offers. And still jio is no one.
