I had purchased jio sim almost before 6 months. But I become very disappointed when I began to use the sim card. I do not know that network connection of jio sim in our area is very poor. So I became very upset after buying jio sim card.The customer service of jio sim is very bad. There is no jio care in our area. The value and chrge of the jio sim is much higher. So It is beyond the middleclass people
