I don't understand the voLTE feature and why it's only sometimes available. It's pretty much whenever I'm on Wi-Fi which I don't get if it's LTE. I also have issues with Wi-Fi calling. Whether I have it set off or set to cellular preferred, it still connects to the voice network over Wi-Fi. I have some issues with the Wi-Fi calls and end up having to redial a call and I have a tower a block away meaning great service so I don't need Wi-Fi calling at home. Does anyone know how I can ensure the Wi-Fi calling won't turn on when I connect to Wi-Fi? Thanks!
