Your issue may be due to WiFi calling being turned off on your phone. Your phone will show that it is connected to a WiFi network but it will not allow for calls to be made when not connected to your service network.

Turn on Wi-Fi calling

Open the Phone app .

Tap More. Settings.

Tap Calls.

Tap Wi-Fi calling. If you don't see this option, it's because your carrier doesn't support this feature. You can use Wi-Fi calling without a service on some carriers.
