I belong to the rural area and I see from since I got jio sim network is very good in our village we can use anywhere.
when I called to the customer they talked very politeness with me and clear any doubt of me. so I can say that the customer service is also very good of jio. But I have some problem regarding to that I think it will be solve soon on the social media.
Now jio is completely fee for the prepaid users and no billing for any person.
