How to disable the VoLTE icon on Xiaomi Redmi: the full guide

Modern Xiaomi and Redmi smartphones feature advanced voice technologies, with VoLTE taking a special place, which stands for Voice over LTE, meaning voice over fourth-generation networks. Device owners often notice an extra HD icon or VoLTE on the screen, indicating that this feature is activated. For most users, this is a boon, as the sound quality becomes crystal clear and the connection is installed instantly.

However, not all situations require this option. Sometimes the carrier does not support the technology in full, causing a malfunction of the mobile Internet during a conversation or quickly dies battery. Also, some users are simply annoyed by the extra icon in the status bar, cluttering the useful screen space.

In this article, we will discuss in detail all ways to manage VoLTE service on Miui and HyperOS devices. We will look at standard methods through system settings, using an engineering menu for advanced users, and also touch on the topic of hidden features that may not be available in your region by default. Understanding these processes will allow you to optimize the operation of your smartphone to your needs.

What is VoLTE and why does the HD icon burn?

VoLTE allows voice calls to be transmitted over 4G LTE channels without switching to older 2G or 3G standards. Before, when you started a conversation, the phone was forced to switch to 3G mode, and Internet speeds dropped to a minimum. With the introduction of Voice over LTE, this problem disappeared: you can simultaneously talk in high quality and download files at high speed. The HD icon that appears next to the network indicator, just signals that the call will pass through this improved channel.

Despite the obvious advantages, the feature may not work properly due to firmware or operator settings. In some cases, the smartphone tries to maintain an LTE connection even when the signal is weak, which leads to communication breaks. There are also situations when the subscriber is in coverage area where 4G is available, but the VoLTE service is not licensed by the operator, which causes constant attempts to reconnect and, as a result, increased energy consumption.

It is important to understand the difference between the display of the icon and the function itself. Sometimes users want to simply hide the icon, leaving the technology on for good sound. Other times require a complete shutdown of the protocol to save charge or solve network problems. Xiaomi provides tools for both scenarios, although access to these can be limited depending on the version of the operating system.

⚠️ Warning: A complete VoLTE shutdown may cause your mobile internet to stop working during a phone call or its speed to drop significantly to the level of the Internet. 3G/2G.

Disable VoLTE via the standard settings menu

The easiest and safest way to manage voice over LTE is to use the standard MIUI interface, which is put on an open menu in most Redmi and Xiaomi models, allowing you to quickly switch network modes. First, you need to open the Settings app and find the section responsible for wireless connections.

Usually, the path to the desired switch is as follows: go to Settings. → SIM-You have to choose a specific SIM card if you have two. Next, look for a item called Use VoLTE or VoLTE Calls. When you put the slider inactive, you turn off voice transmission through the phone. 4G, pin HD disappear from the status line.

In some cases, especially on global firmware versions, this item may be called differently or hidden if the operator has not certified the service. If you do not see the switch, try activating 4G mode preferably in the network type selection menu. Sometimes the VoLTE option only appears after this action, and it is also worth checking whether Do Not Disturb mode or other profiles that may block status display are activated.

☑️ Pre-switch check

Done: 0 / 4

If the standard method fails or the menu item is missing, it may mean that the settings are blocked by the operator or hidden by the manufacturer, and in this situation, they move to more complex methods that require entering special codes or using an engineering menu. 90% of users of the standard path through SIM-Mobile and mobile networks are sufficient to manage the function.

Using the Engineering Menu for Hidden Settings

When regular funds fail, the engineering menu comes to the rescue, a hidden part of the system designed to test equipment by engineers. On Xiaomi smartphones, access to it is often limited, but there are ways to activate. One of the most effective methods is using a special code in the Phone application. Type in the command # # #86583##. If done correctly, you will see a message VoLTE Carrier check was disabled (or enabled), which removes the operator's lock on the display of settings.

Once you unlock the carrier check, go back to the standard network settings menu, and now you'll see a VoLTE switch that didn't exist before. If you need to go deeper into the radio settings, you can try the code ##4636##. It opens the Testing menu, where you can find advanced network settings in the Phone Information section, and sometimes you'll find a Set preferred network type that affects 4G and VoLTE.

Be careful when changing the settings in the engineering menu. Incorrectly setting the frequencies or network modes can cause the phone to stop seeing the network at all. If you change any parameter and the connection is lost, just restart the device - most of the radio module settings are reset when you restart. It is also worth noting that on new versions of Android and HyperOS, access to these codes may be closed, and then you will need third-party applications.

⚠️ Attention: Engineering menus are for professionals, changing unknown parameters can lead to unstable operation of the communication module or complete absence of the network.

What do I do if the codes don't work?
If the code #86583## fails, your firmware version may block this method. In this case, try using the Shortcut Master app to find hidden system activities, or install a third-party launcher that can access system settings. Also helps to temporarily change the region in the phone settings to India or Nepal, where VoLTE is the standard. Apps to activate functions If embedded codes do not work, users often turn to third-party utilities from Google Play. Applications like Force LTE Only (4G/5G) or Activity Launcher allow you to access the system, where the manufacturer actively wants to switch systems to run them. You will need to give them special permissions to use such programs. Often you need access to usage statistics or permission to display on top of other windows. Once you run the application, find the section related to IMS (IP Multimedia Subsystem) or VoLTE in the list of activities. Activating the corresponding switch should return the missing option to the standard menu or immediately turn on the function. It is worth considering that the effectiveness of such methods depends on the Android version and the processor model. On devices with Snapdragon processors, success is higher than on MediaTek, where the radio module settings are often hard-stitched. In addition, the method can block the system security updates from such applications, so it is not guaranteed to work at 110%. Method complexity of risk effectiveness of settings SIM-Maps Low No High Engineering Codes Average Average Average Third Party Applications High Depending on Root Right Model Very High Critical Maximum Impact of VoLTE on Autonomousity and Internet Speed Many users wonder how much VoLTE affects the Internet Theoretically, the technology should save power, because the phone doesn't have to jump between standards all the time. 3G and 4G. However, in practice, in areas of uncertain reception, modem can consume more power, trying to maintain a stable system. LTE-If you notice that the phone is warming or discharged quickly in, you should try to turn off the function. As for Internet speed, VoLTE plays a positive role here. Without this technology, when an incoming or outgoing call is made, the network rolls back to the 3G (H+), where the speed is much lower. With Voice over on LTE You stay online. 4G/5G, It allows you to continue to navigate, stream music, or load pages without interruption, and for gamers and those who are waiting for important messages in messengers during a conversation, this is critical. If your carrier doesn't support VoLTE officially, but the icon is on, Calls may simply not pass or break after a few seconds. 3G/2G (Auto) for stability of communication, sacrificing Internet speed, especially when traveling to regions with poor coverage. HD It's burning, but the calls don't pass or the person you're talking to can't hear you. IMS. In this case, it is recommended to reset the network settings. Go to Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. This action will not delete your personal data, but return the network settings to factory values. Another common problem is that the icon disappeared on its own after the system update. This happens when the new version of the Xiaomi firmware changes certificates for operators. The solution is one: check for updates for the Operator Services or Sim Toolkit application in the GetApps store or Play Store. Sometimes it helps to simply reinstall the SIM card on its own after the system update. This happens, if the provider does not even supports the service. Call your carrier’s support team to see if VoLTE is activated on your number and if your current SIM card is compatible (old SIMs may not support you). 4G voice). ⚠️ Note: When resetting network settings, you will have to re-enter passwords from Wi-Fi networks and reintroduce Bluetooth devices. 💡Connectivity stability is more important than having a beautiful icon. If VoLTE is causing a crash, it's better to turn it off for the sake of a confident reception (FAQ) Is it safe to turn off VoLTE completely on Xiaomi? Yes, it's absolutely safe for the hardware of the phone. You just switch the modem, the only consequence is the reduced sound quality and the possible inability to use the Internet while talking. Why only one operator has a VoLTE icon? This depends on whether the operator has an agreement with Xiaomi and whether his network is on the whitelist of firmware. APN access points, which may differ from provider to provider. Does the VoLTE shutdown affect the ability to receive calls? No, you can receive and make calls as usual, just they will go through standard channels. 2G/3G. The exception is when your network has already been disconnected. 2G/3G, And then without VoLTE, the connection could go missing. Can you just remove the icon, leave the function on? MIUI You can't do that. You can only hide the icon without turning it off through modified firmware or system edits that require Root rights, which is not recommended for ordinary users. Do you need to reflash the phone if VoLTE doesn't work? Most of the time, you don't need to flash it back. Just check your settings, update the software to the current version or change the region in the phone settings. Flashing is required only in rare cases of version incompatibility.
