Jio is the good step towards the digital India. It gives awareness to people about 4g services. And free 4G services and free unlimited calls and messages are another milestone. I was using it from october 20th and till today it was providing good network even in least signal zones also. But only disadvantage is as the no. Of users increasing the signal problems are arising and also we cant estimate the future of jio after 31st. But till that time use unlimited 4G Network and free calls happily.
