Reliance jio is a best network because of jio Internet plans. In India Internet users were 354 million in 2015 after that in 2016 jio was introduced and that's why Indian Internet users continuously increased to 427 million after that in 2017 jio Internet users increased to 503 million until March 2017. In other words we can say in Internet usage India ranked 55th in the world before the jio was introduced but after the jio introduced Internet users in India increase so much that's why India raised almost a number one in the world in terms of internet users, this is a big impact of a jio in the world of Internet users.
Jio gives those internet plans which provide high speed data as well as unlimited calling, before jio introduced we never thought we will get this kind of a plan someday but jio make it possible because of the jio plans other companies like Airtel Vodafone Idea which provide 250 India rupees plan for 1 GB four G data now providing so much cheap data because of the impact of a jio Reliance internet 4g plans. Recently Airtel provided Internet plan of 399 rupees where you can get 1 GB 4g data everyday and this plan for 84 days which is same as jio 399 rs plan.
Jio also has another plan which is a 506 rupees where you can get a to GB data everyday and this Internet pack's validity is 56 days with unlimited calling.
