Can't enable wi-fi calling on iPhone 6+
I try to enable Wi-Fi calling. When I tap Enable, it brings up a page "Change your emergency 911 address". My only options are to "Change Address" or "Cancel". I tap Change Address, and the next page shows my correct address. I click Verify Address, and a pop-up says "Wi-Fi Calling Emergency Address Updated" I click OK, and it brings me back to the page "Wi-Fi Calling on This iPhone", with the slider set to off. I move the slider to On, and it simply repeats the above steps. How can I get it enabled?
