Whenever I don't have volte featured phone, that everytime I have to use this annoying app in my phone. Seriously this app is so much irritating to me. This app is not working in a emergency and even normal time too. As per my experience If your internet is not working then you can't call to anyone because this app is only working if your internet is working.
I become mad to connect my jio sim to this app. It always shows that you don't have a network or internet connection. So I have to call from my another number or dial a number from my family's phone. I called to its customer care but they have only one answer that Our team is working on it. I hope that The Reliance company will resolve this issues. Thanks
