I respect mr ambani to giving free internet to all , but indians always follow free things , this can sell more jio sim , but internet speed is reducing day by day like hell . the main use of this sim card was high speed 4G , I welcome all the steps mr ambani has been taken but they should provide good quality , I am not able to call by this sim card , yes so bascially I need dual sim card mobile phone , this is kinda big problem , I am using iphone 6 , but I am not able to call , this made me numb , so for network I will go with airtel but its really expensive , common man is just doesn’t know which service provider he should use
