I can't make wifi calls and no icon for VoLTE and VoWiFi appear in status bar.
Ensured Wi-Fi calling and VoLTE was enabled in Graphene settings and phone app.
When placing a call while connected to Wi-Fi I never see the wi-fi call icon, even with very bad cellular service.
If I enable airplane mode and turn Wi-Fi on and attempt a call I get the error "Turn off airplane mode or connect to a wireless network to make a call"
dialing ##4636## show invalid or not supported code
IMS Service Status shows that VoLTE and VoWiFi are enabled
Is this an issue with Graphene, my device, or with my carrier?
