Reliance Jio is such a best telephone operator in the today. I have using idea card from last 8 years but the when jio launched I have been purchased jio card and after having fast internet speed I felt in love with the Jio. Future plans of Jio is lower than the other companies as per the company announcement. but till 31 Dec 2016 its totally free and calls and internet is totally free. Range is very good. I have daily travelling but I find the range everywhere so no range issue to the network. if you are looking for the change then jio is the best choice.
