First of all I would say that this jio concept is totally ambani’s smart move to white all that black money in the name of public welfare as he might have took those warnings by modiji seriously on black money. I feel like this JIO sim and sort of all software in MY JIO app including this Jio4GVoice is like a stigma in the name of providing 4g service.
This literally works arbitrarily. As I did not have the phone which would support VoLte so I had to use Jio4GVoice in order to place calls and messages either. But the quality of service this app provides deserves deep criticism. Most of the times it reiterates that all the line to this route is busy whenever you place a call. And barely once in about 5-6 attempts you will get connected. Messaging service is also frustrating as sometimes it sends your message after resending it 15-20 times. And call drops is the major issue as I guess this is one factor which irritates me the most about this app.
