Jio has made so much costomers in very short period of time.ofcourse by providing what others are not.jio made people switch to 4g directly from 2g.3g wasnt even properly established in india and jio snatches the opportunity from it very brutely.its voice calling is great( once your call is connected) , data is great too and the other features like text messeges are given free as complimentry stuff.in a nutshell. Jio, jeete raho!
