Hi I am Jay I am writing my first review about Reliance Jio. I am feeling very lucky because recently I got Reliance Jio Sim which is very hard to get because of their Free unlimited 4G Data till December 2016. So after using Jio 4G I am sharing my experience this Jio will give you good speed not comparable to Vodafone or airtel 4G but still it is very fast I am getting upto 8-10 MBPS which is good also there Network is good sometimes it gives you call drops but still it is in its inception so we can understand it. the speed is good it varies from various locations but you can trust on it. Jio also offering unlimited voice calling till December 2016, and some JIo Services like Jio Tv, Jio Music, jio play, jio Drive etc So Enjoy it you will definitely like itl
