How to get Verizon WiFi Calling to work on new iPhone X I just activated an iPhone X on Verizon Wireless. My previous iPhone was able to do WiFi Calling on my home network. 

Now when I try to turn WiFi Calling on (Settings -> Cellular -> Wi-Fi Calling), I get an error message telling me to contact Verizon.
I restarted my iPhone and was able to activate WiFi Calling with no issues.
