The jio network is really a good deal in term of internet but it is not good for calling purpose . when data is on then a little few call get connected but when we off the data then no call get connected and from its own it get disconnected without saying busy.or any other thing then for calling it has to be improved too much without improving calling it is not possible to make grip on market then I will suggest the company have to solve this issue as soon as possible to attract the customer in this company for long term usage. And for making primary sim or no as jio network.
