I am using it from September it internet speed is very high at performance at least 5mb/s but I don't like it's calling performance the call takes place after 3 -4 times after calling it's internet speed is good when I use youtube it buffers once only till end it's welcome offer and happy new year offer I liked most but it's data limit is reduced to 4gb to 1gb and it is easy to use it's app such as jio tv , jio cinema , jio mags and jio music are also better 1lakh + musics 700+ movies but the jio is only 4g it is not for 2g and 3g which I not liked
