In this article, all working ways to deactivate, including hidden settings and commands for power users.

Method 1: Disable VoLTE via standard MIUI settings

The easiest method is to use a built-in menu, which is suitable for most models on MIUI 12-14, but may not be available on devices for the Chinese market or with custom firmware.

If previous methods have failed, the ADB (Android Debug Bridge) option remains, but it requires a smartphone connection to a PC and basic command line knowledge.

What you need:

Method 4: Delete VoLTE configuration files (requires root)

For root-right users, there is a radical method of removing the system files responsible for VoLTE, which is guaranteed to disable the technology, but can lead to unstable network operation.

Files to delete (the path may differ depending on the model):

• /system/etc/ims/ is a folder with an IMS configuration (including VoLTE).
• /system/vendor/rfs/msm/mpss/readme is the modem configuration.
• /data/data/com.android.ims/ – User data of IMS.

Method 5: Reverse firmware or switch to custom assembly

If VoLTE is forced to activate at the firmware level (for example, on MIUI 14 for the POCO X5 Pro), the only reliable way is to roll back to an older version or install an alternative firmware such as Pixel Experience or LineageOS.

Compatibility table with VoLTE disabling:

🔹 Important: When rolling back to old firmware via Fastboot, use the fastboot flash all command (not the fastboot update) to avoid conflicts with the current anti-rollback version. On models with Snapdragon 888 (for example, Mi 11), version mismatch can lead to a "bricket" (inoperability) of the device.

What to do if VoLTE turns on itself after a restart

Some Xiaomi users are faced with VoLTE activating automatically after a reboot or firmware update, which is due to the operator’s policies or built-in scripts in MIUI.

Decisions:

• 📵 Blocking through Magisk: Install the Disable VoLTE module from the Magisk repository.It modifies system files to prevent forced turn on.
• 🔄 Automation with Tasker: Create a task that performs when booting the system ADB-Settings put global volte_enabled 0.
• 📡 Change of operator: Some operators (e.g, Tele2 In Russia, VoLTE is not supported at the network level, so the technology can be permanently disabled.
