Added (1). Why does my iPhone 6 say At&t Wi-Fi up top and then shows the indicator that i'm on Wi-Fi? It used to just say At&t and then the Wi-Fi indicator if i was on Wi-Fi.

AT&T Wi-Fi calling is available.

When I click it, it comes up with the options "Voice Control," "Favorites," "Device," and "Home." What is this? Is is some kind of new update? Is there a way to get rid of it?
