How to completely disable VoLTE on Xiaomi Redmi Note 8: 5 working ways

Xiaomi Redmi Note 8 is still popular due to its balanced performance and reliable performance. However, many users face the problem of forced VoLTE connection (voice over 4G), which does not always work steadily: call interruptions, poor hearing or fast battery discharge. In this article, we will discuss how to disable VoLTE on the Redmi Note 8 in all available ways, from standard settings to hidden commands.

It’s important to understand that VoLTE (Voice over LTE) should theoretically improve communication quality, but in practice operators do not always implement it correctly. For example, in roaming or at the border of the 4G coverage area, a smartphone can “hang” when switching to 3G, which either does not pass or interrupts calls. In addition, some users note that after activating VoLTE, the battery dies faster – this is associated with constant maintenance of a connection to the 4G network even in the background.

We tested all methods on the Redmi Note 8 with MIUI 12.5, MIUI 13 and MIUI 14 firmware (including global and Chinese versions).If your carrier does not support VoLTE or you just want to return classic calls over 3G, the following instructions will help solve the problem.

1. disable VoLTE via standard MIUI settings

The easiest way is to use the built-in options, but depending on the firmware version and operator, the menu may differ.

• 📱 Your operator does not support VoLTE for this SIM-Cards (for example, some virtual operators).
• 🔄 On the smartphone installed custom firmware, where the function is hidden.
• 📶 The phone automatically switches to VoLTE only in areas with stable 4G-signal.

⚠️ Note: After VoLTE is disabled in some regions, calls may be temporarily interrupted when switching between regions. 4G and 3G. This is normal behavior, the smartphone reconnects to the network. If the problem persists for longer than 30 seconds, check the settings. APN (see section 4).

Disconnection via the engineering menu (code ##4636##)

If the standard settings don’t work, you can use the hidden engineering menu, which works on most Xiaomi smartphones, but you need to be careful not to change other settings so as not to disrupt the network.

After that, VoLTE will be disabled at the communication module level. Please note that in some MIUI firmware, the engineering menu may be blocked. If the code does not work, try the alternative method from Section 3.

3. Alternative method: use of USSD-commands of the operator

Some mobile operators allow you to manage VoLTE settings through USSD-This is true if the smartphone does not provide direct access to the function. Below are commands for popular Russian operators:

6. Radical-method: replacement of firmware or core

If VoLTE is turned on automatically even after all the manipulations, the reason may be firmware with rigidly prescribed operator settings, in which case it will help:

• 📱 Install custom firmware (e.g. LineageOS or Pixel Experience) where VoLTE is managed flexibly.
• 🔧 Replacement of the modem core (radio-firmware) with a version without forced VoLTE.
