The Reliance jio is a very nice sim but there is going indifference with the 3g user and the Reliance jio internet speed is very low. Due to the limited internet used in one day is giving dissatisfaction to many customer .The customer service is very bad.The reliance jio should have used in 3g phone also because no can can buy a new 4g phone just to used Reliance jio.So they should also think about the 3g user.
