VoLTE on Xiaomi Redmi Note 7: how to disable and is it worth it?

Xiaomi Redmi Note 7 is one of the most popular smartphones of the brand, but its owners often face problems when using VoLTE technology (voice over 4G). Despite the promised improvement in call quality, many users complain of sudden communication interruptions, fast battery drain or incompatibility with some carriers. If you too have faced these difficulties, our material will help to figure out how to completely disable VoLTE on your device – and whether to do it.

In this article, we will look at all the available methods, from standard MIUI settings to hidden parameters of the engineering menu, explain what consequences can have deactivation of VoLTE, and provide alternative solutions for stable communication. Importantly, the procedure may differ depending on the version of the firmware and operator, so we took into account all the nuances for Redmi Note 7 (codename lavender).

Before you start, check whether the communication problems are really related to VoLTE. Sometimes the fault is APN settings, incorrect firmware or hardware malfunctions. If in doubt, use our diagnostic table in one of the sections below.

What is VoLTE and why do they want to turn it off?

VoLTE (Voice over LTE) — voice technology 4G traditional 2G/3G. In theory, it should provide clearer sound, faster connectivity, and the ability to talk and use the mobile Internet at the same time. 7 clash:

• 📞 Call breaks – especially when moving between coverage areas or on the subway.
• 🔋 Increased battery consumption - module 4G It works harder than 3G.
• 📡 Roaming problems – not all operators support VoLTE abroad.
• 🚫 Inability to call – if the network 4G It is unstable, and fallback on 3G fails.

In addition, on the Redmi Note 7 with custom firmware (such as LineageOS or Pixel Experience), VoLTE may not work properly due to the lack of operator certificates, in which case disabling the technology becomes the only way out.

On the other hand, deactivation of VoLTE has disadvantages:

• ⚡ Longer connection – calls will be made via 3G, It takes 1-2 seconds longer.
• 📶 Inability to use the Internet during a conversation (if the operator does not support the SV-LTE).
• 🔊 The deterioration of sound quality is especially noticeable in noisy rooms.

Method 1: Disable VoLTE via standard MIUI settings

The easiest and safest method is to use built-in system options, which is suitable for most versions of MIUI (including MIUI 12/13/14) and does not require root rights or special knowledge.

1. Open the Settings app (the gear icon on the desktop).
2. Go to section. SIM-maps and mobile networks.
3. Choose yours. SIM-card (if two of them).
4. Tap on Network Type or Preferred Network Type (the name may vary).
5. In the menu that opens, select 3G/2G (auto) or 3G Only. This will force VoLTE to be disabled, as the technology only works via 4G.

If your menu doesn’t explicitly mention VoLTE, but there’s an option called Voice Call over LTE (or VoLTE), just move the slider to the Off position.. On some firmware, this item may be hidden in Additional Settings → Mobile Network.

Make sure the status bar has disappeared. HD VoLTE|Check the network type in Settings → The phone. → Status. SIM-map|Make a test call - the connection must pass through 3G|Restart your phone to apply changes-->

⚠️ Note: On some firmware (for example, MIUI Global for India) VoLTE option may be blocked by the operator, in which case try other methods or contact the provider support.

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

If standard settings don't work, you can turn off VoLTE via the Engineering Mode, a method that requires caution, as incorrect changes can disrupt the network.

Instructions for Redmi Note 7:

1. Open the phone app and enter the combination: ##4636##
2. In the menu that opens, select Phone Information (or Phone Information).
3. Scroll down to the Set preferred network type block.
4. Choose LTE only or 3G only (depending on whether you want to disable 4G entirely or VoLTE only).
5. Press Turn off radio, then turn it back on with the Turn on radio button.

To completely disable VoLTE (while saving 4G for the Internet), follow the following steps:

1. Go back to the main menu of the engineering mode and select Telephony → VoLTE.
2. Set the VoLTE Provisioned Flag option to Disabled.
3. Reboot the phone.

If ##4636### doesn’t work, try the alternative code for Qualcomm chips (installed in Redmi Note 7):

##86583##

⚠️ Note: Changes to the engineering menu are not saved after resetting or updating the firmware, Tele2 In Russia) can automatically enable VoLTE through server settings.

Method 3: Disabling VoLTE through Settings SIM-map

Not everyone knows, but some problems with VoLTE are solved at the level of the Internet. SIM-For example, if you use eSIM or a virtual operator (MVNO), Technology can be unstable. Here's what we can do:

1. Extract. SIM-phone-card.
2. Check if your tariff supports VoLTE. check with the operator or on its website (section "Coverage and technology").
3. If you use dual SIM, try swapping slots (e.g., moving a card from slot 1 to slot 2).
4. Update profile SIM-map: 📱 For MTS: send SMS textual 1234 room 1234. 📱 For Beeline: dial *110*181# and press "Call". 📱 For MegaFon: use it USSD-team *505#. 📱 For Tele2: send out empty SMS room 111.

If VoLTE is activated again after the profile update, try to force reset your network settings:

1. Go to Settings → System → Resetting of settings → Resetting of network settings.
2. Confirm the action and restart the phone.

💡

If you travel frequently, turn off VoLTE before traveling abroad, and many foreign operators do not support this technology for roaming subscribers, which may cause calls to be stopped at all.

Method 4: Software disabling VoLTE (without root)

If previous methods didn't work, you can use third-party applications, which don't require superuser rights, but their effectiveness depends on the version of MIUI and the operator, and we tested the following tools on the Redmi Note 7:

• 📌 4G Switch – allows you to switch between 3G/4G and disable VoLTE. Link to Google Play.
• 📌 Network Signal Guru — shows the current type of network and allows you to block VoLTE.
• 📌 LTE Discovery -- analyzes network parameters and suggests optimal settings. Useful for diagnosing problems.

Instructions for using 4G Switch:

1. Install the application and provide all the permissions requested.
2. Choose yours. SIM-main-menu map.
3. Slip on Disable VoLTE (disable VoLTE).
4. Confirm the action and restart the phone.

Important: Some antiviruses (like Avast or Dr.Web) may block such applications, considering them "potentially dangerous." This is a false positive - add the utility to the exceptions.

⚠️ Note: Network management applications may conflict with system services MIUI. If after using them, mobile communication is lost, reset the network settings (Settings) → Resetting settings → Resetting network settings).

What to do if the VoLTE is not shut down?

If none of these things work, the problem can go deeper, and here are the most common causes and solutions.

If you use custom firmware (such as LineageOS or AOSP), VoLTE may not work due to lack of IP Multimedia Subsystem (IMS) certificates.

1. Check if your firmware supports VoLTE for your region (information is usually available on a developer forum, such as XDA Developers).
2. Install the IMS Patch patch (if available for your version).
3. Return to official MIUI if communication stability is critical.

💡

If you are not sure about your actions, you should contact the Xiaomi service center. Incorrect manipulation of network settings can lead to complete loss of communication, and it will be difficult to restore it without specialized equipment.

Alternative solutions: if you disable VoLTE is not possible

If deactivating VoLTE has not solved the communication problem, consider alternative options:

• 🔄 Turn on the "Only" mode 2G" — This is guaranteed to disable VoLTE and provide stable calls (though without the Internet). → SIM-map → Type of network → Only 2G.
• 📶 Use Wi-Fi Calling – if your carrier supports calls over Wi-Fi (such as MTS or MegaFon), this can be a good replacement for VoLTE. → SIM-map → Wi-Fi Calling.
• 🔧 Update your radio module – sometimes VoLTE problems are solved by updating your modem (radio firmware.
• 📱 Change device – if the Redmi Note 7 doesn’t support stable VoLTE performance with your carrier, consider switching to a better-compatible model (like the Redmi Note 10 or the Redmi Note 10). POCO X3).

It is also worth checking whether the problem is hardware, for example, a faulty RF module (radio frequency) can cause VoLTE to malfunction.

• Poor quality of communication even in the area of confident coverage.
• The phone does not catch the network after restarting.
• Constantly switching between 2G/3G/4G for no reason.

In such cases, only repairs in the service center will help, the average cost of diagnosing a communication module is from 500 to 1500 rubles.
