I am user of reliance jio first we will talk about its network. reliance jios network is totally worst network I have seen ever. reliance jios network not working in villages and thats the worst thing about its network. and the second we talk about customer service is very good. billing and charges is also very good only the network who givng us 3 months of free internet and calls for only 300 rupees so its charges and billing are great. but if we talk about this all things then the worst was reliance jios network.
