Modern smartphones Samsung Galaxy are equipped with a variety of advanced features designed to improve connection quality. One of these options is Wi-Fi Calling, which allows you to make voice calls and send messages over a wireless internet connection instead of a standard cellular network. This solution is ideal for areas with poor mobile coverage, but in some situations, users may need to disable this feature.
A common issue is incorrect switching between networks, when the phone "clings" to a weak Wi-Fi signal instead of a stable 4G or 5G, resulting in interrupted calls. This feature can also consume additional battery power or interfere with roaming when traveling abroad. In this article, we'll take a detailed look at how disable Wi-Fi Calling on different Samsung models and different versions of the operating system.
Shell interface One UI The app is constantly updated, and the settings layout may vary slightly depending on your Android version and device model. Below are universal methods that will help you quickly restore default call settings. We'll cover both software-based methods via the menu and hidden engineer codes.
Why you might want to disable Wi-Fi calling
Although technology VoWiFi Voice over Wi-Fi (Voice over Wi-Fi) is considered useful, but in practice, it doesn't always work perfectly. Many users notice that when a call comes in, their smartphone doesn't automatically switch to the mobile network, even if the cellular signal is excellent but the Wi-Fi is weak. This results in the caller hearing a metallic noise, echo, or the conversation suddenly ending when leaving the router's range.
Another common reason for disabling this feature is the specifics of roaming. Some carriers may charge Wi-Fi calls as international calls, even if you're on your home Wi-Fi network abroad. To avoid unexpected charges, experienced travelers prefer to disable this option completely before their trip.
⚠️ Please note: If you disable Wi-Fi Calling, connection quality may be reduced in basements or buildings with thick walls, as your phone will rely solely on the base station signal.
Furthermore, there are situations where the function simply conflicts with specific router models or corporate network security settings. In such cases Samsung The device may constantly scan for available networks for calls, which leads to increased power consumption and heat buildup. Disabling this option helps stabilize the device and extend battery life.
The standard way to disable it is through the settings menu.
The easiest and safest deactivation method is to use the smartphone's native interface. The steps may vary slightly depending on the OS version. One UI, but the general logic remains the same for most models Samsung GalaxyYou don't need any third-party apps or root access.
To begin, unlock your device's screen and locate the default "Phone" app. It's typically located on the bottom taskbar and has a green icon with a phone. This app controls basic voice communication settings.
☑️ Function disabling algorithm
After entering the settings menu, find the option for internet calling. In newer firmware versions, it may be called "Wi-Fi Calling" or "Wi-Fi Calling." Move the slider to the inactive position. The system may ask you to confirm this action; agree to it.
If you don't find the item you need in the Phone app, try an alternative route through the general system settings. Click Settings → Connections → Mobile network. There may also be a switch located here that allows disable Wi-Fi Calling on your device. This method is especially relevant for models of the series Galaxy A And Galaxy M.
Instructions for different versions of One UI and Android
Samsung regularly updates its software, changing the menu structure. For users of older models, such as Galaxy S8 or Note 9, running on Android 9 or 10, the interface may seem unusual. In these OS versions, the path often lies through Settings → Apps → Phone → Wi-Fi Calling.
Owners of current flagships such as Galaxy S23 or S24 with shell One UI 6.0 Users with iPhone 8 and above may notice the integration of call settings into a single control center. Here, the option may be hidden within the "Additional Features" menu or only available with a SIM card from a specific carrier. It's important to understand that the presence of the switch itself depends on the carrier profile programmed into the device.
⚠️ Note: The menu layout depends on your carrier's firmware. If you have a custom firmware or a device imported from another region, the menu may differ from the standard one.
On devices running Android 12 and 13, this feature is typically located in a separate subsection in the top notification shade. You can simply swipe down twice from the top to find the "Wi-Fi Calling" icon and tap it to change the status. If the icon isn't there, edit the Quick Settings panel to add the necessary toggle.
What to do if the menu is empty?
If you don't see Wi-Fi Calling in your phone's settings menu, your carrier doesn't support this feature or hasn't provided the appropriate settings profile for your SIM card. In this case, a forced deactivation isn't necessary, as the feature is inactive at the network level.
Using the engineering menu and codes
For advanced users who can't find the settings they need in the standard interface, there's the option of using service codes. This method allows accessing hidden diagnostic menus. Be careful: changing unknown parameters in the engineering menu may cause instability in the communication module.
Open the Phone app and dial the combination ##4636##This is a universal code for Android devices that opens the testing menu. However, on many modern smartphones Samsung This code may be blocked by the manufacturer. In this case, try the specific code. *#27663368378#, which opens the Wi-Fi configuration menu.
*#27663368378#
In the menu that opens, find the item related to VoWiFi or WFC (Wi-Fi Calling). Here you can force network priority or completely disable Wi-Fi for voice calls. After making changes, be sure to restart your device for the new settings to take effect.
It's worth noting that in the latest security updates, Samsung blocks access to these codes on global firmware versions. If the code doesn't work, the system will simply ignore the input or open the standard menu. In this case, you can only rely on the default settings or contact your carrier.
Settings via your carrier profile
It is often forgotten that service management Wi-Fi Calling This is not only on your phone but also on your carrier's end. Even if you've disabled the feature in your smartphone's menu, the network may still attempt to initiate a connection if the service is active on your plan. To completely disable it, you need to log into your mobile operator's account.
In your carrier's app (e.g., My MTS, Megafon, Beeline, or Tinkoff Mobile), find the services or plan section. There should be a toggle switch that enables or disables Wi-Fi calling. Disabling this option ensures the network won't route your calls over the internet protocol.
- 📱 Go to your mobile operator's app.
- 🔍 Find the "Services" or "Price and Options" section.
- ❌ Find the "Wi-Fi Calling" option and disable it.
- 💾 Save the changes and restart your phone.
You can also use USSD commands, which are specific to each operator. For example, to deactivate a service, a code is often used. 111... (The numbers depend on the operator.) It's best to check the exact combination on the official website or in the support chat, as codes are subject to change.
Comparison of operating modes and possible problems
Understanding the differences between these modes will help avoid confusion. When this feature is active, your phone can operate in different priority modes. Some carriers allow you to choose whether to prioritize "Prefer Wi-Fi" or "Prefer Mobile Network." If you simply want to disable the feature, either mode must be disabled.
Let's look at the main differences in device behavior with different settings:
| Parameter | Wi-Fi Calling Enabled | Wi-Fi Calling is Off |
|---|---|---|
| Quality in the basement | High (via Wi-Fi) | Low or no connection |
| Switching networks | Breaks are possible | Stable via GSM/LTE |
| Battery consumption | Above (constant search) | Standard |
| Roaming | Risk of paid calls | Safe (local number) |
One common issue after disabling this feature is the disappearance of the "HD" or "VoLTE" icon in the status bar. Don't worry, this is normal, as these technologies are often linked. Sound quality may change, but connection stability generally improves.
If after all these steps your phone continues to attempt to make calls via Wi-Fi (which can be detected by the icon in the status bar or by the behavior during a call), try resetting your network settings. This will reset all modem settings to factory defaults, clearing any possible software configuration errors.
Diagnostics and Frequently Asked Questions
If you've completed all the steps and the issue persists, it could be due to a software conflict or an outdated firmware version. Check for system updates in the Settings → Software UpdateSamsung often fixes communication module errors in security patches.
It's also worth checking if you have any third-party calling apps (such as Google Phone, Viber, or Skype) installed that could be hijacking the audio output. Make sure that Wi-Fi calling isn't enabled in these apps' settings.
Does disabling Wi-Fi Calling affect internet speed?
No, disabling this feature only affects voice calls and SMS. Internet data transfer speeds (browsing, video, messaging) will remain the same and will depend solely on the quality of your Wi-Fi router or cell tower signal.
Is it possible to disable the feature for only one SIM card?
Yes, if you have a dual-SIM smartphone. In the call settings menu (Settings → Connections → Mobile network) you can select a specific SIM card and individually disable the Wi-Fi Calling option for it, leaving it active on the second SIM card.
Why does the setting re-enable itself after rebooting?
This can happen if the service is forced to activate on the operator's end. In this case, it's essential to deactivate the service through your personal account or the operator's USSD code; otherwise, the phone will receive an activation command every time it logs into the network.
Will 4G/LTE work for calls after the shutdown?
Yes, if your carrier supports VoLTE (Voice over LTE). Disabling Wi-Fi Calling switches calls to standard cellular protocols (2G/3G/4G), but does not disable the mobile network itself.
Do I need to remove the SIM card to reset the settings?
No, you don't need to remove your SIM card. Network settings can be reset using the software, via the "General Settings" → "Reset" → "Reset Network Settings" menu. This is safe for your personal data (photos, contacts), but it will delete saved Wi-Fi passwords and Bluetooth settings.
