    Works however it does lock up if you have it on WiFi preferred and leave WiFi. NOTE: you may not know there is a connection issue until you don't receive calls or texts for a few hours and wonder why. Turn off WiFi calling, turn phone off, turn back on it should work.

    This app works fine with stay connected with wifi. When you out of your Wi-Fi you have to turn the phone off for 30 seconds and turn the phone back ON to make it working. It works good on my SGS3. I only give 5 stars when this issues fix. I really love this feature. Please fix it!

    Honestly I don't see what folks on here are talking about I have wp8.1 and its works just fine yes when I initiate wi-fi calling it will alert me that my 911 address is missing but wait a minute or so and it boots up and works just like it is supposed to a little patience goes a long way people 5 stars because it does in fact work
