I have not been able to get Wi-Fi Calling working since the last operating system update. I am no longer able to make calls or receive texts while using wifi calling. I have a Galaxy Note 8.
There are some known errors with that model. Are you getting a location timeout error?
Howdy Bassiswild. With the newer update, the 911 tagging feature has been changed. Prior to the update this feature used GPS to tag the location. Now this tagging is dependent on a LTE signal. If the LTE signal is not strong enough the WiFi calling will time out.
