How to Enable VoLTE and VoWiFi on Xiaomi (Root/Non-Root)

Sadique Hassan•Updated Jan 21, 2022

In this guide, we will show you two different methods through which you could enable VoLTE and VoWiFi on your Xiaomi device. Owing to the plethora of benefits involved, Voice over LTE and WiFi have been the go-to choice for the users. If we talk about the latter, then it removes your dependency from the carrier as you could easily place and receive calls via your WiFi. As far as LTE goes, many users had to do a recharge for both their data pack and talk time. But now they could eliminate the latter and directly ake calls via their data packs.

All in all, both these features behold quite a lot of perks. However, not everyone is able to make full use of these features. In some instances, the carrier seems to have blocked it whereas sometimes, it is the case of geo-restricted blocking. So even if your device supports these features you wouldn’t be able to try them out. Well, that isn’t the case any longer as this guide will show you the steps to enable VoLTE and VoWiFi on your Xiaomi device. So without any further ado, let’s get started.

How to Enable VoLTE and VoWiFi on Xiaomi

There exists a root and a non-root method of carrying out this task, and we have listed both of them below. Go through both of them once and then try out the one that is in sync with your requirement. While it is along the obvious lines, we would still like to reiterate the fact that your carrier at least needs to supports both the VoLTE and VoWiFi in the first place.

If that is not the case, then obviously this guide would be of no good. Droidwin and its members wouldn’t be held responsible in case of a thermonuclear war, your alarm doesn’t wake you up, or if anything happens to your device and data by performing the below steps.

Enable VoLTE and VoWiFi on Xiaomi without Root

To begin with, you will have to disable the carrier check for VoLTE. So bring up the dialer and type in the below command:
```
*#*#86583#*#*
```
After that, you will need to disable the carrier check for VoWiFi. So bring up the dialer again and type in the below command:
```
*#*#869434#*#*
```
Now head over to Settings > SIM and Cellular and select your SIM Card.
Then scroll to the end and enable the toggle next to VoLTE and VoWiFi.
Next up, head over to the Play Store and download the Shortcut Maker app.
Now launch the app and select Activities.
After that, scroll to the Modem Config, tap on it to expand it, and then select MBNLoader.
Then tap on the Try this shortcut button.
You will now see a long list of MBNLoader, each having different regions.
You could verify it from the details mentioned right beneath them. They will be of the following format:
```

```
So refer to the region section and select any random one. Then close the app and restart the device.
Check if it enabled VoLTE and VoWiFi on your Xiaomi device or not. If it’s still not enabled, then this time select a different region and retry.

You will have to do so until it works out. Though it does calls for some efforts, it would prove to be worth the investment in the end. On that note, we conclude this section on how you could enable VoLTE and VoWiFi on your Xiaomi Device using the non-root method. Let’s now show you how this could be carried out on a rooted device.
