How to completely disable VoLTE on Xiaomi: 5 proven ways

VoLTE Technology (Voice over) LTE) lets you call through 4G-But many Xiaomi users are facing problems like sudden call breaks, fast battery drains, or incompatibility with some carriers. 2G/3G — This article will help you understand how to disable VoLTE on Xiaomi in any convenient way.

It’s important to understand that the process differs depending on the smartphone model, the MIUI version and even the firmware (global, Chinese, custom). We tested all methods on current devices — from the budget Redmi Note 12 to the flagship Xiaomi 14 Pro — and collected only working solutions, and also analyze why sometimes VoLTE turns on itself and how to prevent it.

Before you start, check whether your operator supports VoLTE. For example, in Russia, the technology is actively used by MTS, Beeline and Tele2, but in some regions it may not work stable. If after the VoLTE shutdown, calls stop passing, then your operator has already completely switched to the service. 4G-voice and there is no alternative.

1. disable VoLTE via standard MIUI settings

The easiest way is to use the built-in system options, which is suitable for most Xiaomi, Redmi and POCO models on the MIUI 12-14.

Open the Settings app and go to the section SIM-maps and mobile networks. Choose your own. SIM-If you have more than one card, then tap on the network type. Here you will see a VoLTE switch (or call to the network type). 4G Turn it off and reboot the smartphone.

• 📱 For two. SIM-maps: VoLTE settings can be duplicated for each slot. disable the option for both cards.
• 🔄 If no point: your operator or firmware is hiding the option.
• ⚡ Quick access: Swipe down from the top edge of the screen, hold the mobile network icon → Type of network.

On certain devices (e.g, POCO F5) The path may be slightly different: → Connections and sharing → SIM-maps and mobile networks → [choose SIM] → Call VoLTE. If the calls are not going through after the shutdown, check if the mode is activated. 4G network-setting.

2.Use of the engineering menu (code ##4636##)

If standard settings don't work, try the engineering menu, which works on most devices, but you need to be careful not to change other settings so you don't disrupt the network.

Open the phone application and enter the combination:

##4636##

From the menu that opens, select Phone Information. Scroll down to the Set preferred network type and select the option without mentioning LTE, such as:

• WCDMA preferred (3G)
• GSM only (2G)
• LTE/WCDMA/GSM auto (auto, but without priority VoLTE)

Once you change, restart your smartphone. On some firmware, after resetting your network settings or updating your MIUI, this parameter may return to factory values. If the operator forcibly activates VoLTE (as MTS does in some regions), this may not work.

💡

Save a screenshot of the current engineering menu settings before the changes, and if the connection goes down, you can return the original settings.

3. Disconnection via MIUI Hidden Settings (for power users)

If standard methods don’t work, try MIUI Hidden Settings (available on Google Play) which reveals hidden system options, including advanced network settings.

Once installed, open the app and go to Network & Connectivity → Mobile Network, where you will find additional switches for VoLTE, ViLTE (4G video calls) and VoWiFi (Wi-Fi calls). Disable all associated options and restart the device.

The app may require ADB rights for some features, and if you're not willing to provide them, skip this option, and note that custom firmware (like LineageOS) may have different paths to customization.

4. disabling VoLTE through ADB-Teams (for advanced teams)

If none of the previous methods worked, the ADB (Android Debug Bridge) method requires a computer and basic command line knowledge.

First, turn on USB Debugging on your smartphone: Settings → About Phone → MIUI Version (tap 7 times to activate Developer Mode) → Return to Settings → Additional → For Developers → Debugging on USB.

Connect your phone to your PC, open the terminal (or Command Prompt in Windows) and type in:

adb shell


settings put global volte_enabled 0




settings put global enhanced_4g_lte 0




settings put global vt_enabled 0




settings put global wifi_calling_enabled 0

Once you've done the commands, restart the device. To return VoLTE, replace the 0 with 1 commands.

⚠️ Attention: Misuse of the right ADB If you're not sure what you're doing, skip this method or get help from a specialist.

5. Reset network settings (last resort)

If VoLTE turns on itself after a reboot or update, try resetting your network settings, which will remove all stored Wi-Fi networks, passwords and mobile settings, but often solves the problem of forced VoLTE activation.

Go to Settings. → SIM-maps and mobile networks → Resetting network settings (or Settings) → System system → Reset → Reset network settings. Confirm the action and wait for the reboot. After that, manually set up the connection to the mobile network by selecting the type 3G or 2G.

✅ Remember. APN-Operator settings (can be found on its website)

✅ Shut down. SIM-card from VoLTE services in the operator's personal account (optional)

✅ Make sure there is enough charge on the phone (minimum 30%)

On some firmware, VoLTE may be activated again after a reset, in which case combine this method with a shutdown via an engineering menu or ADB.

What to do if the VoLTE is not shut down?

If neither of these methods worked, the problem could be on the operator's side, with some providers (e.g. MTS in Moscow or Beeline in St. Petersburg) forcibly activating VoLTE at the network level, in which case:

• 📞 Call in support of the operator and ask to disable the service "Voice on" 4G" or "VoLTE" for your number.
• 🔄 Put it in. SIM-card to another phone (not Xiaomi) and disable VoLTE there - sometimes settings are saved.
• 📶 Try using it. SIM-A card of another operator (such as Tele2 or Yota) where VoLTE is not activated by default.

Also check if your device has an operator application (such as My MTS or My Beeline) that sometimes automatically activates VoLTE, delete them or disable auto-start in the battery settings.

💡

If after all the manipulations, VoLTE is still active, your operator has completely switched to the Internet. 4G-There's no alternative, and in that case, you just have to accept it or change the provider.
