Relience jio is a mobile network developed by Relience pvt.ltd. At first it had provided free 4g internet. After that certain cheap plans were introduced by jio with unlimited voice calls all over India. This is the full story behind jio. My view and opinion about jio is mixed. First of all like would like to mention that if you use jio you should have another sim in your phone. Because it is hardly ever possible to make a call from jio in one go. It is the thing that I really hate in jio. But at the same time it had done many good works. It had helped to digitalize India and had hapled in providing 4g connectivity to the peoples who could’nt affort it. It also helped in growing the popularity of Youtube in India. Many unemployed people who have no source of income have started making money from Youtube. ( I know that this review is becoming long and I apologise for that. ) At last I would like to say that if jio improve its signal strengths then it have the potencial of becaming one of the greatest network not only in India but also internationally.
