Wi-Fi Calling on the Honor 50 Lite: How to Fix or Fix Connection Issues

Honor 50 Lite — a popular smartphone with technology support Wi-Fi Calling (VoWiFi), which allows you to make calls over the internet instead of a cellular network. However, many users encounter the problem that the feature is activated automatically when calling Wi-Fi connection problems, dropped calls, or conflicts with other devices on the network. In this article, we'll look at how to completely disable Wi-Fi calling, configure their correct operation or troubleshoot typical problems associated with this function.

It is important to understand: Wi-Fi Calling on the Honor 50 Lite may conflict with some routers, especially if features like Smart QoS or MAC address restrictions are enabled on the network.The problem also often occurs when connecting to public networks (in cafes and airports), where certain ports are blocked. Before disabling the feature completely, try optimizing your settings—this may preserve the ability to make internet calls without interruption.

If you're determined to get rid of Wi-Fi calls, below is an algorithm for different firmware versions. Magic UI (including global and Chinese builds). We'll also consider alternative methods if the standard method doesn't work.

Why Wi-Fi calls are interfering with the Honor 50 Lite

VoWiFi technology is supposed to improve connectivity, but in practice it often becomes a source of problems. Here are the most common scenarios when users want to disable it:

• 📶 Constant Wi-Fi drops: the smartphone connects and then loses the network, especially during active calls.
• 🔋 Increased battery consumption: background activity of the VoWiFi module increases power consumption by 15–20%.
• 📞 Calls don't get through: subscribers hear "unavailable", although the network is available, and SMS messages are received normally.
• 🔒 Conflict with VPN: When VPN is enabled, Wi-Fi calls may be blocked by your ISP.
• 🌐 Problems with roaming: In some countries, VoWiFi is unstable or requires additional settings.

The root of the problem lies in how Honor 50 Lite Implements VoWiFi support. Unlike flagship models, it lacks flexible network priority settings (LTE vs. Wi-Fi for calls), and the algorithms for switching between cellular and Wi-Fi sometimes work incorrectly. For example, the smartphone may become stuck on a weak Wi-Fi signal, ignoring a more stable cellular network.

⚠️ Attention: On some firmware versions Magic UI 4.2 and below, disabling Wi-Fi calling through the settings menu may reset after a reboot. In this case, you will need to edit the system settings (see the section about ADB).

Method 1: Disable Wi-Fi calling through your phone settings

The easiest method is to disable the function in the menu. The instructions apply to most versions. Magic UI (including global and European assemblies):

1. Open the app Settings (gear on the desktop).
2. Go to the section Mobile network (or SIM cards and mobile networks).
3. Select your SIM card (if you have two).
4. Find the item Wi-Fi calls (may be called VoWiFi or Wi-Fi calling).
5. Move the slider to the position Off.
6. Confirm the action if a warning appears.

After disabling, restart your smartphone. If the item Wi-Fi calls is not on the menu, which means:

• 📱 Your operator does not support VoWiFi (check with your provider).
• 🔄 The function is hidden in the engineering menu (see Method 3).
• 🔧 Firmware update required (check in Settings → System → Software Update).

Method 2: Disabling via the engineering menu (for advanced users)

If the standard method doesn't work, you can try deactivating VoWiFi via engineering menuThis method is suitable for firmware versions where the function is hidden from the user. Be careful: Incorrect changes in the engineering menu may disrupt the network operation.

Instructions:

1. Open the app Telephone.
2. Enter the combination: ##2846579## (For Magic UI 4.2+) or ##4636## (universal code).
3. In the menu that appears, select ProjectMenu → Background Settings → Wi-Fi Calling.
4. Find the parameter Wi-Fi Calling Switch and set the value Disable.
5. Save the settings and restart your phone.

If the combination doesn't work, try the alternative code: ##86583## (Network testing menu). The path may differ in some versions: Network Setting → Wi-Fi Calling Config.

⚠️ Note: On Chinese versions Honor 50 Lite (model NTH-AN00) the engineering menu may be blocked. In this case, use ADB (Method 4).

What should I do if the engineering menu doesn't open?

If nothing happens after entering the code, check:

- Are there any spaces or typos in the combination?

- Does your antivirus/firewall block access to system functions?

- Is the firmware updated to the latest version?

As a last resort, try entering the code through the Phone app in dialing mode (not through the keypad).

Method 3: Using ADB to force shutdown

If the previous methods did not help, there remains Disable VoWiFi via debug bridge ADBThis requires connecting your phone to a computer, but is guaranteed to work on any firmware. You'll need:

• 🖥️ Computer with Windows/macOS/Linux.
• 🔌 USB cable (original, with data transfer support).
• 🛠️ Utility ADB (download from the official Android Studio website).

Step-by-step instructions:

1. Turn it on on your phone Developer mode: go to Settings → About phone and press 7 times Build number.
2. Return to Settings → System → Developer Options and activate USB debugging.
3. Connect your phone to your PC and confirm debugging permission.
4. Open Command Prompt (or Terminal) and type:

adb shell settings put global wifi_calling_enabled 0
adb shell settings put global volte_provisioned 0

After executing the commands, restart your smartphone. To check if the settings have been applied, enter:

adb shell settings get global wifi_calling_enabled

If the answer is 0 — the function is disabled.

Configuring your router for stable VoWiFi operation (if you don't want to disable it)

If you don't mind using Wi-Fi calling but want to troubleshoot connection issues, optimize your router settings. Problems most often arise due to:

• 🔄 Frequent channel changes (the router automatically switches to the busy channel).
• 🛡️ Port blocking (VoWiFi uses UDP port 500 And 4500).
• ⚡ Bandwidth shortages (prioritize traffic for your phone).

Recommended router settings:

If your router supports guest network, create a separate access point specifically for your phone with traffic priority. Also, check if your provider VoWiFi traffic (relevant for some corporate or educational networks).

Common mistakes and their solutions

Even after disabling Wi-Fi calling, users Honor 50 Lite You may experience side effects. Let's look at common problems and how to resolve them:

• 📵 "No network" after disabling VoWiFi: Restart your phone and manually select your carrier in Settings → Mobile network → Network operators.
• 🔄 The function turns on automatically: Check if the firmware has been updated (sometimes resets occur after OTA updates). Also, clear the app cache. Telephone.
• 📞 Regular calls don't work: Maybe it switched off VoLTETurn it on. Settings → Mobile network → Advanced → VoLTE.
• 🔌 Wi-Fi connects, but the internet doesn't work.: Reset network settings in Settings → System → Reset → Reset Wi-Fi, mobile networks, and Bluetooth.

If you've lost sound in calls after using VoWiFi, check:

1. Is the mode not activated? On the plane (even if the icon is not lit).
2. Are there any background data restrictions set for the app? Telephone.
3. Does VoWiFi conflict with apps like Truecaller or WhatsApp (temporarily remove them).

Alternatives to Wi-Fi calling on the Honor 50 Lite

If you've disabled VoWiFi but want to keep making calls over the internet, consider these alternatives:

• 📱 VoIP applications: WhatsApp, Telegram, Skype or Zoiper (support Wi-Fi calls without being tied to an operator).
• 🔗 Call forwarding: Set up call forwarding to another number via Settings → Calls → Call Forwarding.
• 🌍 Local SIM cards with roaming: Some virtual operators (like Tinkoff Mobile or Yota) offer favorable rates for calls over the Internet without VoWiFi.

Suitable for business or frequent international calls Google Voice (requires US number) or Zoom Phone (paid, but with advanced features). If integration with a native dialer is important to you, try enable only VoLTE (calls via 4G without Wi-Fi):

1. Go to Settings → Mobile network.
2. Select a SIM card.
3. Activate VoLTE (the item may be called 4G calls).

⚠️ Attention: On some firmware versions Honor 50 Lite Simultaneously activating VoLTE and disabling VoWiFi may cause the IMS module to fail. If the network is lost after making these changes, reset the network settings (Settings → System → Reset).
