I have a jio phone. I am using it more than 3 months. It has a good rear camera but front is not so good. It has 4gb internel storge. But it have only one sim slot in that slot I use jio sim only. Speed of 4g is good voice quality is also come in hd. It is little bit heavy but looks stylish. It have a jio store for apps and the jio phone is laging and hang some times. But in this price range it is better than other mobiles.
