After buying Reliance Jio sim, 3 months later I used my Idea Sim. I just called my friend and share my location, I just talked about few seconds they charged about 2 rupees for that, I belive they took me as theire enemy after I bought My Jio sim.?????? But, idea have a better network coverage and Recharge coupons availabe in all stores. A big Demerit is Charging for Internet and Call charge. It is killing an Average person in Modern india
