VoLTE and VoWiFi doesn't work

[Popica]

Zenfone 9/ Android 13/  33.0804.2060.100/ Romanian operators My sims work on VoLTE and VoWiFi in another phone.

The mobile operators shut down the 3G networks and all calls switch to 2G, until those are shut down as well. Therefore, the voice is not always clear and there are localization problems when calling the emergency services.

1) Try dialling *#*#3642623344#*#*    It won't show anything but WiFi calling will be enabled

2) Go to settings and enable WiFi calling

Thank you. It partially worked, but it worked, thanks. However, the team of developers must say why after the restart VoLTE and VoWiFi disappear from the menu and don't work anymore. The code must be entered again and functions are activated.
