How to disable VoLTE on Xiaomi: full instructions for all models

VoLTE Technology (Voice over) LTE) It allows you to send voice calls through 4G-However, many Xiaomi users have situations where this feature needs to be temporarily or permanently disabled. from connection problems to battery savings or conflicts with a communications operator.

In this article, we will discuss in detail all ways to disable VoLTE on Xiaomi, Redmi and POCO smartphones, both through standard settings and through the engineering menu, pay attention to the features of different versions of MIUI (including MIUI 14 and HyperOS), and also consider what to do if the VoLTE disable button is missing or gray settings. A separate section is devoted to the consequences of technology deactivation and alternative solutions for stable communication.

Why you might need to turn off VoLTE on Xiaomi

Before we get to the instructions, it is important to understand when a VoLTE shutdown is justified.

• 🔋 Fast battery discharge. VoLTE requires a constant connection to the battery. 4G-On some Xiaomi models (e.g. Redmi Note 10 Pro or POCO X3 Pro) this can reduce battery life by 10-15%.
• 📶 Connection problems in regions with unstable surfaces 4G VoLTE can cause call interruptions or inability to make an outgoing call, especially for operators with poorly optimized networks.
• 🔄 Conflict with other functions, like some firmware MIUI Simultaneous activation of VoLTE and VoWiFi (wi-fi calls) leads to failures.
• 📱 Operator Compatibility: Not all mobile operators support VoLTE on Xiaomi devices, especially if the smartphone is purchased abroad (for example, the global version of Xiaomi). 13T network of the Russian operator).

It is important to note that disabling VoLTE does not affect mobile internet speed – you will still be able to use it. 4G However, voice quality can deteriorate, especially if your carrier does not support the transmission. 3G (For example, in some regions of Russia after the shutdown 3G-network).

Method 1: Disable VoLTE via standard MIUI settings

The easiest way is to use the built-in options. The interface may vary slightly depending on the version of MIUI and the smartphone model, but the general logic is maintained.

1. Open the Settings app (cog icon).
2. Go to SIM cards and mobile networks (or Mobile network on some models).
3. Choose. SIM-The card you want to disable VoLTE for (if you have two SIMs).
4. Find VoLTE Calls (or VoLTE, 4G Voice Calls).
5. Move the slider to the off position.
6. Confirm action if the system requests a reboot.

On some devices (e.g. Xiaomi 12 Pro or Redmi K50), the option may be in the submenu Additional Settings → Calls. If you don't see the VoLTE option, try an alternative path:

Settings → About Phone → MIUI Version (click 7 times to activate Developer Mode) → Return to Settings → Additional → Developer Options → Network Settings → Disable VoLTE

Note: On HyperOS firmware (e.g. Xiaomi 14), the path may be different: → Mobile network → Name. SIM-map → Type of network → VoLTE.

Method 2: Disconnect via the engineering menu (for power users)

If the standard method does not work (for example, the option is gray or not), you can use the engineering menu, which requires caution, as incorrect changes can disrupt the network.

Instructions for most Xiaomi models:

1. Open the Phone app.
2. Enter the combination: ##4636### (on some models it may not work – see the alternatives below).
3. In the menu that opens, select Phone Information (or Phone Information).
4. Scroll down to the Set preferred network type block.
5. Select LTE/WCDMA/GSM auto (PRL) or WCDMA/GSM auto (without mentioning VoLTE).
6. Click Turn off VoLTE provisioning (if there is one).
7. Go back and restart the device.

If #4636### doesn’t work, try the alternative codes:

• #86583## is a direct VoLTE engineering menu (on some models).
• ##2263## - RF Band menu (can contain VoLTE settings)

Attention! Changes to the engineering menu can lead to:

• Losing the net.
• Wrong job. SIM-map.
• Necessity to reset network settings.

⚠️ Note: Some Xiaomi models (e.g. Redmi) 9A or POCO M3) After changes in the engineering menu, the mobile Internet may disappear. In this case, return the settings to the original state or reset. APN: Settings → SIM cards and mobile networks → Access points (APN) → Reset to factory.

Method 3: Disable VoLTE with ADB (for advanced users)

If previous methods didn’t work, you can use Android Debug Bridge (ADB), which is suitable for devices with an unlocked bootloader and the developer mode turned on.

Step-by-step:

1. Activate Developer Mode: Settings → About Phone → MIUI version (click 7 times).
2. Return to Settings → Additional → Developer settings and enable USB debugging.
3. Connect your phone to your PC, install Xiaomi drivers (if necessary) and check the connection with the command: adb devices
4. Execute the command to disable VoLTE: adb shell settings put global volte_enabled 0
5. To disable ViLTE (video calls on the 4G) Adb shell settings put global settings vt_enabled 0
6. Reset the device.

To return VoLTE back, replace the 0 by 1 commands above.

⚠️ Attention: Use ADB This can lead to loss of warranty if the device is not officially unlocked through the Mi Unlock Tool.In addition, incorrect commands can cause failures in the communication module!

What to do if VoLTE does not turn off: common problems and solutions

Sometimes users are faced with a situation where the VoLTE option is blocked (gray slider) or is not in the settings.

• 🔒 The operator blocks the change of settings. Some mobile operators (for example, MTS or Beeline in Russia) link VoLTE to the Internet. SIM-Solution: Try inserting SIM another operator and check for the option. contact the operator support to request that VoLTE be disabled for your number.
• 📱 The firmware does not support manual control of VoLTE. MIUI. Solution: Update your firmware to the latest version (via Settings) → The phone. → Update system.Install custom firmware (e.g. xiaomi.eu) where the option is unlocked.
• 🔧 Failure in network settings. Reset helps: Settings → SIM cards and mobile networks → Resetting network settings
• 🛠️ Hardware problem: Some devices (for example, after a fall or repair) may be damaged communication module, in which case VoLTE cannot be turned off - requires diagnostics in the service center.

If neither method worked, check to see if VoWiFi (wire-fi calling) is activated. On some firmware, the two options are linked, and disabling VoWiFi can automatically deactivate VoLTE.

Settings → SIM cards and mobile networks → [Select SIM] → VoWiFi calls

💡

If VoLTE has lost mobile internet after shutting down, try manually selecting a network type: go to Settings → Mobile Network → Network type and set up 4G/3G/2G (auto) to help restore the connection without VoLTE.

Consequences of turning off VoLTE: what will change in the phone

Before you turn off VoLTE, it's important to understand what changes it will make, and here are the main consequences:

Particular attention should be paid to compatibility with the operator.

• In Russia after the blackout 3G-networks (MegaFon, Beeline) on some tariffs without VoLTE calls may become impossible.
• In Europe and Asia, many carriers have already switched to VoLTE entirely, and turning it off will result in a drop in 2G connectivity (which will significantly worsen the quality of the connection).

If you travel frequently, we recommend that you check with the operator before turning off VoLTE whether alternative voice technologies are supported in roaming.

💡

Disabling VoLTE is only advisable in cases of communication problems or critical battery discharge. In all other situations, it is better to keep the function active - it provides a more stable and quality connection.

Alternative solutions: how to improve communication without turning off VoLTE

If your goal is not to turn off VoLTE, but to solve a specific problem (such as call cliffs or fast battery drain), consider alternative methods:

• 📶 Forced network selection. Instead of completely shutting down VoLTE, try manually prioritizing the network: → Mobile network → Type of network → 4G (only LTE) This can reduce the number of switches between 4G and 3G, charge-saving.
• 🔄 Resetting settings APN. Incorrect access point settings can cause VoLTE to crash. Reset them to factory: Settings → SIM cards and mobile networks → Access points (APN) → Menu (three dots) → Reset to factory
• 📱 Update of firmware. New versions MIUI HyperOS and bugs associated with VoLTE are often fixed. Check for updates: Settings → The phone. → Updating the system
• 🔋 Optimize power consumption. Instead of turning off VoLTE, limit the background activity of applications: Settings → Battery and productivity → Battery consumption management

If the problem is due to a bad signal, try:

• Use VoWiFi (wi-fi calls) in areas with low 4G coverage.
• Buy a signal repeater (4G amplifier) for your home or office.
• Change the tariff plan to the one that is better optimized for VoLTE (check with the operator).
