if VoLTE/VoWIFI was working before the update, by clearing the Phone app data/cache (and SIM activation app) should restore VoLTE/VoWIFI.
be aware that codes applied toggles between enable/disable carrier check.
to get it work the phone should reply with message "disabled carrier check" after dial the code.
if applied again will "enable check" and that will inhibit VoLTE/VoWIFI (will gray out the option).
Where can you find the sim activation app?
