VoLTE (Voice over LTE) technology allows you to call over 4G, promising clearer sound and faster connections. However, on Xiaomi smartphones — whether it’s the Redmi Note 12, POCO X5 or the flagship Mi 13 — this feature sometimes brings more problems than benefits. Users complain about missed calls, fast battery drain or unstable mobile Internet during a conversation. If you encounter such difficulties, turning off VoLTE can be the solution.
In this article, we’ll look at 5 proven ways to deactivate VoLTE on Xiaomi devices, from standard settings to hidden engineering menus and ADB commands. Also, we’ll find out which models (like the Redmi 10C or POCO F4) can lose functionality after a shutdown, and what it can do in roaming. If you’re not sure if you need to do it, there’s a checklist at the end of this article to make a decision.
1.What is VoLTE and why do they want to disable it
VoLTE (Voice over LTE) is a 4G voice technology that replaces the outdated 2G/3G standards. In theory, it should improve the quality of communication, but in practice Xiaomi users are faced with:
- ⚡ Increased battery consumption - module LTE It is more active than normal calls.
- 📵 Missed calls – especially on MediaTek devices (e.g. Redmi Note 11).
- 🌐 Roaming problems – some operators (e.g. Tele2) do not support VoLTE abroad.
- 📶 The drop in Internet speed during a conversation on old firmware MIUI.
Also, on budget models (Redmi A2, POCO M5), VoLTE can conflict with Wi-Fi Calling, which leads to connection breaks. Before you turn off the feature, check if the problem is temporary - sometimes rebooting or resetting network settings helps.
Method 2: Disabling VoLTE through standard settings
The easiest method is to use the MIUI menu. It is suitable for most modern devices (Xiaomi 13T, Redmi Note 12 Pro+, POCO F5, etc.), but may not be available on older models (for example, Redmi 9A with firmware below MIUI 12).
Instructions:
- Open the Settings app (cog icon).
- Go to the SIM cards and mobile networks section.
- Choose yours. SIM-card (if two of them).
- Click on Network Type or Network Settings.
- Find a VoLTE switch (can be called Calls) 4G or HD-call and turn it off.
If there is no VoLTE, then your operator does not support this function on your website. SIM-map MIUI It hides the option. In this case, try the following methods.
☑️ Preparing for VoLTE shutdown
Method 2: Engineering menu (for advanced users)
If VoLTE is not disabled through settings, you can use the engineering menu, which works on most Xiaomi devices, but requires caution - wrong actions can disrupt the network.
Steps:
- Open the Phone app.
- Enter the combination: ##4636### (some models, such as the POCO X3 Pro, may require #86583##).
- Select Phone Information (or Phone Information).
- Scroll down to the Set preferred network type section.
- Select the LTE/TDD-LTE/CDMA/EvDo/GSM/WCDMA option without mentioning VoLTE.
- Save the changes and restart the device.
⚠️ Attention: On some firmware (MIUI 14 for Xiaomi 12) the engineering menu can be blocked. If nothing happens after entering the code, try using the ADB (4).

Method 3: Disconnection through SIM-menu
Some operators (for example, MTS, Beeline) allow you to manage VoLTE settings directly through the SIM-This method is the most secure, as it does not affect the system files Xiaomi.
How to check:
- Open the Phone app.
- Enter. USSD-your operator's team: MTS: *111*545# Beeline: *110*180# MegaFon: *105*495# Television2: *155*1#
Management of services → VoLTE
If the carrier doesn't provide this option, try calling support and asking them to turn off VoLTE on your number.
| Operator. | USSD-team | Support for shutdown |
|---|---|---|
| MTS | *111*545# | Yes (via menu or support) |
| Beeline | *110*180# | Yes (only for 4G tariffs) |
| MegaFon | *105*495# | Partially (depending on region) |
| Tele2. | *155*1# | No (only through support) |
| Yota | *100*1# | No data. |
5. Method 4: Disabling VoLTE via ADB (for experienced)
If previous methods have failed, you can use Android Debug Bridge (ADB), which is suitable for all Xiaomi devices, but requires a computer and basic command line knowledge.
Step-by-step:
- Turn on Developer Mode on your phone: Go to Settings → About Phone. Tap 7 times on MIUI Version.
USB debugging
Settings → Additional → For Developers
ADB
Android Developers
cmd
adb shell
settings put global volte_enabled 0
settings put global enhanced_4g_mode 0Reset the device.
⚠️ Attention: On some firmware (MIUI 13 for Xiaomi 11T) team ADB To fix the changes, use the Shizuku app or create a script to automatically execute commands when you boot.
settings put global volte_enabled 1
Check if the operator is blocking regular calls without VoLTE (relevant for Tele2 in some regions).-->
6. Method 5: Reset network settings (extreme case)
If VoLTE continues to work despite all the manipulations, the last option is to reset the network settings, which will delete all stored Wi-Fi networks, passwords and mobile settings, but sometimes helps to “reset” the VoLTE settings.
How to do this:
- Go to Settings → Reset settings.
- Select Network Resetting.
- Confirm the action and wait for the reboot.
After discharge:
- ✅ VoLTE will be disabled by default (unless the operator forcibly activates it).
- ❌ You will have to re-enter Wi-Fi passwords and configure them. APN.
💡
Network resetting is the most radical method, and only use it if other methods fail, as it removes all the stored networks and may require reconfiguration of the Internet.
7 Consequences of turning off VoLTE: what you will lose
Before you turn off VoLTE, evaluate the possible disadvantages:
| Xiaomi model | What happens after the VoLTE shutdown | Recommendation |
|---|---|---|
| Redmi Note 12, POCO X5 | Calls will go through 3G, the speed of the Internet during the conversation will drop | Disconnect if there is a battery problem |
| Xiaomi 13, 13 Pro | Wi-Fi Calling may stop working | Check your Wi-Fi Calling settings after switching off |
| Redmi 10C, POCO M4 | Roaming calls may not be made (depending on operator) | Turn it off only if you are not traveling. |
| Xiaomi 12T, 11T | The sound quality will deteriorate (no) HD-call-up) | Alternative: Turn off VoLTE for second SIM only |
Special attention should be paid to roaming, for example, Tele2 in some countries (Turkey, Egypt) requires VoLTE for outgoing calls, and if you travel abroad often, it is better to leave the function on and solve the battery problem in other ways (for example, to turn off the background activity of applications).
8. Alternatives to disabling VoLTE
If VoLTE is needed for quality communication, but side effects interfere, try:
- 🔋 Optimize battery consumption: Turn off Network Search in roaming (Settings) → SIM-map → Activate the Adaptive Battery (Settings) → Battery).
- 📶 Switch to switch to 3G For calls: In the Network Type, select 3G/2G (car 4G/3G/2G.
- 🔄 Update the firmware: In new versions MIUI 14+ Fixed VoLTE bugs for Redmi Note 11 and POCO F3.
Also check if VoLTE conflicts with other features. For example, on Xiaomi 12 Lite, the dual window (split screen) does not work at the same time as VoLTE during a call.
