Wi-Fi calling stopped on my phone the week of April 6th in Napa, CA. I've troubleshot with the support chat team and went through all options of resetting network settings, etc., but nothing is working. Is there an issue with this feature in this area of California?
I live in area code 82414, and Wi-Fi Calling works just fine. There is probably an issue with how Wi-Fi Calling is provisioned on your account and phone.
