In this comprehensive tutorial, we will show you the steps to enable VoLTE and VoWiFi on Xiaomi 12, 12X, and 12 Pro devices. In recent years, more users are getting inclined toward voice-over LTE or WiFi. The reason for the same is the plethora of benefits associated with it. For example, you could directly place a call via WiFi (WIFi Calling) even if there is no carrier network signal.
Likewise, you wouldn’t even have to carry out any additional recharges just for the sake of talk time. However, while most devices come with this technology, not everyone keeps it enabled by default. Unfortunately, the latest Xiaomi flagships also fall in this domain. But fret not. Using a simple workaround you could easily enable VoLTE and VoWiFi on Xiaomi 12, 12X, and 12 Pro devices. And this guide shall make you aware of just that. Follow along for the instructions.

Note
Please note that this will enable only the option in settings in case it is hidden. It will not make VoLTE/VoWiFi work if the phone does not support it.
Xiaomi can´t enable the option if the carrier doesn´t verify/grant Xiaomi permission to do so. Testing this is a very tedious process.
If VoLTE/VoWiFi is not working for you after toggling it on in settings, this means there´s no config file for your carrier yet.
In my case, VoLTE was already supported by default. I could enable VoWiFi with the third prop because Xiaomi already has the correct config in the modem. Lucky for me it works and it was only a matter of making the option visible.
It might be enabled by default in the future if the carrier agrees.
