Your sim card provider needs to have wifi calling available for VoWIFI to work. If they do then you can disable carrier check and see if the option appears VoWiFi/WLAN *#*#869434#*#* type that in the phone's dialer. You can type it in a second time to enable it again

Finally, using dial codes and clearing of network and wifi settings, Volte and VoWifi are active in phone sim card settings. Unfortunately, dial history do not indicates Volte cals, I also was not able to start VoWifi call when using flight mode with wifi enabled. Phone test (using dial code *#*#4636#*#*) shows Volte and VoWifi as disabled. Sim card provider declares that these services are available. How to check where is priblem?

Yes, all these codes are suitable, Volte and VoWifi options in Sim card settings are "On". But wifi calling still do not work. And I'm not sure regarding Volte calls, while pictogram is shown but in call history no information about Volte.

For me neither... After latest update V12.0.2.0.QJKEUXM VoWiFi not working at all, and VoLTE dissapears every little... Before that update everything was fine... They broke something obviously because with RN 8 Pro I don't have problem.

Wifi calling is not supported in Lithuania. Volte in action could be estimated by quick connection between 2 Volte users, additionally - ability to use good quality internet browsing during call (explanation of mobile services provider)
