Realince jio gives you 1gb per data along with free calling and msg . the best part of jio is that it is 4g network and givea u everything free for a period of time . If I talk about its bad part that many times call not connect and if you are in a close room the network strength is weak and sometime network disappear anthor draw back of jio sim is speed .The speed not looks like a 4g speed ., . And it vary from place to place . but I till now dont think to make it my main sim which I can use for long time anthor big draw back of realince jio is that those who have 4g lte phone can call or recive call when they open data connection that even jio drawback .but still jio givea us free data we are thankful to them
