Reliance Jio is the very fastest growing sim in the market.It gives 4g data for unlimited for 3 months and also unlimited call and message free for three months.The sim was easily available in the jio store or some local mobile customer service provider.You just have see that your mobile must be 4g supported then just download jio and then verify from you emi mobile number and then go to store he will give you sim and you can enjoy for free for 3 months.I like the sim because the network was fully ranged any where as we see other operators does not give some local or rural area but it has totally range any where.Go and just grab sim and enjoy the seevices.
