In this article, we will analyze all the current ways to deactivate VoLTE on this model, including hidden settings MIUI and engineering menu.

It's important to understand that VoLTE is not just a 4G voice, it's a technology that affects the stability of communications. On the Redmi Note 8 Pro, it can not work properly due to firmware or regional operator limitations. We tested all methods on the latest versions of MIUI 12/13/14 and identified those that are guaranteed to work.

Attention! On some firmware (e.g. MIUI 12.5 Global), the VoLTE option can be hidden even in developer mode, in which case move on to the following methods.

Method 2: Use of the Engineering Menu (USSD Codes)

If standard settings do not allow you to disable VoLTE, you can use the engineering menu, which works on all versions of the Redmi Note 8 Pro, but you need to be careful - wrong actions can disrupt the network.

Follow the steps:

1. Open the Phone app.
