Disabling VoLTE on Xiaomi Redmi 8 Pro: all the ways and nuances

Why do users want to turn off VoLTE on Redmi 8 Pro?

VoLTE Technology (Voice over) LTE) Improves the quality of voice communication by transmitting voice through 4G-Networks instead of traditional 2G/3G. However, in practice, the owners of Xiaomi Redmi 8 Pros face a range of challenges, from fast battery discharge to unstable connections, especially in areas with poor coverage. LTE, where the phone is constantly switching between networks, wastes energy searching for a signal and ends up performing worse than with VoLTE disabled.

Another common reason is conflicts with telecom operators: Some Russian and foreign providers have not yet optimized VoLTE for all Xiaomi models, which can interrupt calls and sound robotic.finally, there are users who fundamentally abandon smart functions for the sake of saving charge or privacy reasons, because VoLTE requires permanent authorization on the network, which can theoretically be used for tracking.

Before you get to the instructions, it’s important to understand: disabling VoLTE on the Redmi 8 Pro doesn’t always solve communication problems – sometimes the root of evil lies in firmware or in the background. SIM-If the call quality has not improved after deactivation, it is worth checking the settings. APN update.

Method 1: Disable VoLTE through standard settings

The easiest and safest method is to use the built-in MIUI options, which does not require superuser rights and is suitable for most firmware versions.

  1. Open the Settings app on the main screen.
  2. Go to section. SIM-maps and mobile networks.
  3. Choose yours. SIM-card (if two of them).
  4. Tapping on VoLTE or VoLTE (the name may vary depending on the MIUI version).
  5. Move the slider to the off position.

After that, the phone will automatically restart the communication module (sometimes you need to completely restart the device). HD or VoLTE in the status bar next to the network indicator.

⚠️ Note: Some Xiaomi firmware may have a VoLTE item hidden. If it's not on the menu, try the way with an engineering menu or update it. MIUI last-minute.

Method 2: Use of an engineering menu (for power users)

If the standard method doesn't work, you can use the Engineering Mode, which is more versatile, but it takes care that the wrong settings can disrupt the network.

Instructions:

  1. Open the phone app and enter the combination: ##4636##
  2. In the menu that appears, select Phone Information (or Phone Information).
  3. Scroll down to the Set preferred network type block.
  4. Select LTE/WCDMA/GSM auto without the VoLTE mark.
  5. Go back and find the VoLTE Provisioning option – turn it off if it’s active.

After this manipulation, the phone will reconnect to the network, and if the VoLTE icon is gone, it was a success. If not, try restarting the device.

What to do if the engineering menu is not opened?
On some Xiaomi firmware, the ##4636## combination is blocked, in which case you can use applications like the MTK Engineering Mode (for MediaTek processors) or Qualcomm Service Menu (for Snapdragon), and note that such programs require superuser rights and may not be secure.

Method 3: Disconnect through system files (for advanced)

If previous methods have not helped, and VoLTE continues to activate automatically, you can try editing system files. ROOT-rights and backup of data.

Algorithm of action:

  1. Install a file manager with ROOT support (such as Root Explorer or Solid Explorer).
  2. Go to /system/etc/ and find the build.prop file.
  3. Open the file in the text editor and add a line to the end: persist.radio.volte_off=1
  4. Save the changes, set the rights to 644 (rw-r--r---) and restart the phone.

If VoLTE is still active after the reboot, check if your settings are overriding the operator settings, in which case a deeper intervention may be required, such as modifying files to the operator. /data/data/.

Before editing build.prop, make sure to back it up. An error in syntax can make it impossible to boot the system.

⚠️ Warning: Changing system files without a backup can lead to permanent loss of communication or even a "brief" of the device. If you are not sure about your actions, you should consult alternative methods.

What if the VoLTE itself is turned on after the update?

Many Redmi 8 Pro users are faced with the fact that after the MIUI update, VoLTE settings are reset, due to Xiaomi's policy, which forcibly activates VoLTE for compatibility with the new communication standards, to avoid automatic activation:

  • πŸ“΅ Reverse to the old version MIUI (If it was stable, use the official firmware from Xiaomi.
  • πŸ”„ Turn off automatic software updates in settings (Settings) β†’ The phone. β†’ Updating the system β†’ Three points. β†’ Update settings).
  • πŸ› οΈ Use Magisk modules like Disable VoLTE (requires) ROOT and established by Magisk).
  • πŸ“± Reset your network settings after each update (Settings) β†’ SIM-maps and mobile networks β†’ Resetting network settings).

If the problem persists, consider custom firmware (like LineageOS or Pixel Experience), where VoLTE settings are more flexible, but this requires unlocking the bootloader and may take away your warranty.

πŸ“Š You are turning off VoLTE on your Xiaomi?
Yeah, through the settings.
Yeah, through the engineering menu.
I tried it, but it didn't work.
No, I don't see the point.
I don't know what VoLTE is.

Impact of VoLTE shutdown on communication quality and battery

Many people fear that deactivating VoLTE will worsen the quality of calls, and in practice it depends on your operator and region:

  • βœ… The benefits of shutdown: πŸ”‹ Increased battery life by 10-15% (due to reduced background activity of the module) LTE). πŸ“Ά More stable connection in areas with weaker 4G-signal (the phone will not attempt to hold VoLTE). πŸ›‘οΈ Reducing the load on the processor (relevant for budget models like Redmi 8 Pro).
  • ❌ Cons of shutdowns: 🎀 Possible deterioration of voice quality in regions with good VoLTE coverage. ⏱️ Longer connection for calls (up to 2-3 seconds delay). πŸ“΅ Loss of Wi-Fi Calling (if it was tied to VoLTE).

To measure the changes objectively, do a test: call another phone with VoLTE on and off, comparing the sound quality, and pay attention to battery life – the difference will become noticeable after 1-2 days of use.

πŸ’‘

Disabling VoLTE does not affect mobile internet speed (LTE/4G) and only voice calls.

Alternative solutions: if VoLTE does not turn off

There are times when VoLTE stubbornly doesn't want to deactivate, and this may be due to:

  • πŸ“± Operator firmware (some custom versions) MIUI block out changing settings).
  • πŸ”§ Hardware restrictions (on some revisions Redmi 8 Pro VoLTE rigidly spelled out in the modem).
  • πŸ“‘ The policy of the mobile operator (for example, MTS or Beeline can force VoLTE to activate for certain tariffs).

In such situations, it will help:

  1. Replacement SIM-Newer cards (sometimes old cards automatically turn on VoLTE).
  2. Reset to factory settings (before that, make a backup!).
  3. Using a second slot for SIM – sometimes VoLTE only works on the main card.
  4. A support letter to Xiaomi describing the problem (specify the MIUI version and phone model).

If nothing works, the radical option is to run the Fastboot firmware with a complete data cleanup, which is a last resort, but it is guaranteed to reset all network settings.

FAQ: Frequent questions about disabling VoLTE on Redmi 8 Pro

Can I turn off VoLTE without it? ROOT-rights?
Yes, in most cases, the standard MIUI settings or the engineering menu (#4636###) are enough. ROOT is only required for editing system files like build.prop.
Why did the mobile internet disappear after the VoLTE shutdown?
This can happen if you select an incompatible network mode (e.g., 3G only) from the engineering menu. Return the settings to LTE/WCDMA/GSM auto and restart the phone.
Will Wi-Fi Calling work if VoLTE is turned off?
Depending on the operator, some providers (e.g. Tele2) link Wi-Fi Calling to VoLTE, and check this information in support of your carrier.
How to check if VoLTE is disabled?
Look at the status bar -- the HD or VoLTE icon should disappear, and you can also call another phone and listen to the quality of the connection: without VoLTE, the voice may sound less clear, but without delay.
Does disabling VoLTE affect the work of messengers (WhatsApp, Telegram)?summary> No, VoLTE only affects voice calls through the operator (4G/Wi-Fi), So their work won't change.
