Jio is one of finnest network which I have seen till now. bcoz of its welcome offer I have purchased it.
as compared to idea, voda, airtel jio has much good internet speed and talking about calling not that which I have wanted .else I am satisfied by it.i think bcoz of free calling there is lot of que in tele world so one has to try 5 to 6 times for a single call.jio is best and will lead the mobile world in upcoming days.
