Jio is probably the most brilliant network currently as compared to others. I have been using Jio since September 2016 till now and does not have any much issues. The main difference between Jio and other service providers is that we get the same benefits at a much lower rates as we all know. Coming to the customer service, Jio was bit disappoint in 2016 when they launched there network in the early stages.
But till then there is no issues with the customer service. Its very good response from the customer support. In case of charges and billing, as I told we get the same amount of benefits at a quite lower rates. So, I think this is the best network till now as compared to the other networks. Hates off to JIO for thinking about the customers rather than just looting for their benefits.
