VoLTE and Wifi Calling on Zenfone 8

[lukasz_szabelsk]

Hi all,
Does anyone know if we can expect enabling VoLTE and Wifi Calling in european networks? I can only see in settings that icons for these options are available to enable at notification bar:


Also as call quality is quite poor, can we expect some improvement with software updates as enabling HD Voice codecs?
Best,
Lukasz

Hej,
I am using Orange Flex in PL and VoLTE/VoWiFi seems to be working just fine. I needed to enable switches in mobile network options by this code: *#*#3642623344#*#* (must be re-entered after the reboot)
Call quality is very good. Confirmed by the people I talked to over the phone.

You are my hero! @bartehk
Confirming that it works in Orange PL (nju)
Quality is just perfect (like on all new VoLTE/VoWifi supporting phones)
Now for me Zenfone 8 is the best phone you can buy in 2021 🙂

This is the code for the orange network only? For me, Tmobile does not work.

No, I believe this is ASUS's code for enabling that options.
I found it in a guide on xda-developers.

For me, after running this code, the wifi calling option appeared (but it does not work). However, VOLTE did not show up. I am in the T-Mobile network and I have active WiFi calling and VOLTE.
