Reliance Jio is the world fastest growing network in the world . I am using this network from past few months .And according to me it is the best network in the world. Its data connection is awful fast but I face slight problem in network in my village.Its comes with free complimentaty apps like jio music, jiomags, jioexpress etc. It customer service is very good .They resolve issues very quickly. This sim comes with postpaid and prepaid plans, also its charges are very low in comparison to other companies .But now its charges are similar to its competative companies .
