I used this sim for 6months and in this 6 months I comes to know that it was not as good as I thought before buying a new sim of jio . when I am going to buy this new sim, on that time time I was feeling very excited for jio 4G.and after few time I comes to know that its speed was decreasing day by day .during night its speed becomes very slow .sometimes I cannot able to make outgoing calls also. so guys this is my experience of jio 4G for now.••.
