Reliance jio very great strategy to target large no of people and they had done pretty well. I am also using reliance jio intially data speed is well till dec 2016 but after that speed is down drastically. Its doest support calling function in mobile like Apple 5c .Also lay back is after Dec 2016 its data caping is 1gb per day I dont think its really 1gb a day.but thik hai reliance is giving free thats best thing. Enjoy its individual choice.
