Network: its network is too for internet, calls, message, and video calling because its gives a free service at the time of demonitization that was to good for all the people of india.
customer: according to me reliance jio solve all the problem of their customer but they take alot of time to receive call of customer.
charge and billing: its a great thing for people of india who use jio sim and their facility. its free of cost. now they started member ship feature for jio customer with Rs 99 and Rs 308.
hope my review will help you.
