I am going to tell you the experience of my father which brought this Jio phone at last month. Before that they use small 2G featured phone, so they buy Jio phone by Man-soon Hangama offer of Jio. After using it they told me some problem about this phone. It has very bad quality of keypad. We can not easily unlock this phone. Sometimes they get hanged. But still Jio phone is best for at their price range. It is cheapest 4G phone in world. Now Jio phone has all essential apps like Facebook, Whats App and much more. It was amazing but still they have above bugs. After that we can not accepted much more from Jiovideocall .My personal opinion was it was best choice for such person who upgrade from 2G to 4G in low price. If any Jio employ read this then solve above problems.
