I personally use before one and half year . I think it is best network that I ever used . I think it is the best network of india.
Network quality is very good of Jio. Even when I am in a village it gives the full network and internet speed is very good.
it the best network that I have used in a village.
customer service is good when you download myjio app and manage your plans .
charges are very low as other network I used 459 plan for 84 days and gives 1 Gb data per day and calling, sms etc.
so I suggest you to go and pick up the plan.
