Question Wi-fi call - Google Pixel 6

I had one Samsung S21 dual sim operating with one SIM card post paid at AT&T in US and the second SIM card pre paid at Vivo Brazil. This configuration allows me to receive text messages from Brazil without pay roaming when using Vivo in US. One feature that amazed me was the fact that using the Vivo wifi call, it works like be in the network in Brazil; plus country code and even area code was not required. To check the voice mail, I can use number like *555 and forward calls using GSM commands to the Vivo network.
I recently changed my phone to Google Pixel 6 where the AT&T became eSIM and operates in the IMEI2/EID and Vivo in the IMEI1. All great features I described above are gone. I can see icons showing the call as wi-fi but doesn't work anymore.
Any comment about is welcome.

I'm Brazilian. I have postpaid of course and when I had s21 ultra, 5G, VoLTE and VoWIFI worked perfectly. Now with pixel 6 pro none of this works. Only with root access through magisk, it was possible to activate VoLTE and 5G. VoWIFI did not work.

At least there is a way to do. You gave me valuable information. I don't like the idea to root the phone and of course in the case of Samsung you will disrupt KNOX. Are there any other option to force the Network type without root the P6? What about *#*#4636#*#* ?

Not. Activation keys for VoLTE and VoWIFI are grayed out. It was only after installing the VoLTE module that these switches became active.

Instalação do módulo VoLTE. Não entendo o o que vc está falando. Sim, os botões estão bloqueados mas não sei como habilitar.

When I say VoLTE module, I'm referring to the modules we install in magisk.

Ok. Understood.

I am in touch with Google to see what they can do. I got an email this morning asking me to give details. Let see what happens.
