I used jio from last starting of september 2016 but I cannot satisfy totally because I do so many hard work to get jio sim añd the main thing is that it cannot support 3g , 4g metwork . Its not bad but not so good . And the other thing is that voice call services is very very bad if you call on any other network it cannot success. Jio to jio calling is good but other network its not good. Yah its data servies is very good but some time I loose my network or data speed . It gives high speed at metro polician cities but its hihg speed dream fails in villages . The areas which are far from cities its fails to give speed that type of places. But overall its good
