Modern smartphones Samsung Galaxy are equipped with a variety of advanced features, one of which is VoWiFi (Voice over Wi-Fi) technology. It allows you to make and receive voice calls over a wireless network, which is especially useful in areas with poor cellular coverage. However, not all users like it when the phone automatically switches to Wi-Fi Calling, especially if the quality of the Internet connection is unstable or traffic pricing raises questions.
Device owners often encounter situations where the voice becomes robotic during a call, delays occur, or the call drops completely when switching between networks. In such cases, it becomes necessary to forcefully deactivate this option, returning to the standard cellular connection. This simple step can significantly improve communication stability in your specific situation.
In this article, we'll take a detailed look at all the possible ways to manage internet calling on devices from the South Korean giant. We'll also review the default operating system settings. Android, the smartphone's menu capabilities, and the nuances of working with different mobile operators. You'll learn how to quickly find the switches you need and understand why they might be hidden.
What is VoWiFi and why should you disable it?
Technology Voice over Wi-Fi This technology transmits voice traffic over IP protocols, similar to how instant messaging apps work, but with integration into the standard phone book and dialer. To the user, it appears like a regular call, but the signal travels not through the operator's base station, but through an indoor access point. This is convenient in basements, offices with thick walls, or rural areas.
However, there's a downside. If the router is overloaded with multiple connected devices or the ISP throttles the speed, connection quality drops sharply. Furthermore, some users prefer to have complete control over which connection is in use at any given time to avoid unexpected charges or problems with location identification for emergency services.
Disabling this feature may also be necessary in situations where the smartphone gets stuck on a weak Wi-Fi signal, ignoring a strong 4G or 5G cellular network. In this case, forcing the phone to switch to cellular service solves the problem of intermittent audio. Understanding how this feature works helps you make informed decisions about its use.
⚠️ Attention: Before disabling this feature, make sure you have reliable cellular coverage in your current location. If you're in a poor coverage area, disabling Wi-Fi Calling may completely block incoming calls.
Disabling the feature through the Samsung smartphone settings
The easiest and most accurate way to manage voice transmission over the Internet is to use the phone's built-in menu. The shell interface One UI from Samsung is quite logical, but the layout of the switches may vary slightly depending on the version Android and device model. Typically, this is done through the main settings menu.
Open the Settings app and find the section related to connections. In modern firmware versions, it's called "Connections." This is where all settings for networking, Bluetooth, and mobile data are located. Look for an item labeled "Wi-Fi Calling" or "Wi-Fi Calling."
Within this menu, you'll see a main toggle switch that activates or deactivates the feature. Its "Off" position completely prevents the phone from using the internet for voice calls. Additional settings are often available here, such as network priority: which is more important for the device—cellular or wireless.
☑️ Disabling algorithm in settings
In some cases, if your carrier doesn't support this feature or your SIM card doesn't meet the requirements, this menu item may be missing. In these cases, you should look for alternative solutions, which are discussed below.
Setup via the operator's app
Often, VoWiFi service management is not only in the user's hands but also controlled by the telecom provider. Major operators offer their own dashboard apps where you can fine-tune your service. This is especially important if the switch is blocked or hidden in the phone's menu.
Log into your carrier's account via a browser or the official app. You'll need the section for communication services or plan options. There may be an option called "Wi-Fi Calling," "VoWiFi," or "Internet Calling." Unchecking the box or toggling the slider in the app will send a command to the network, disabling the service at the carrier level.
This method ensures that the phone will not attempt to initiate an internet connection, even if the device's settings allow it. This is the most reliable method, as it works regardless of reflashing or resetting the phone to factory settings.
| Operator | Section in the application | Service name | Peculiarities |
|---|---|---|---|
| MTS | Services / Archive | Calls via Wi-Fi | Requires activation on the tariff |
| Beeline | Main / Services | Wi-Fi calling | Works automatically |
| Megaphone | Communication services | Calls via Wi-Fi | Available to all subscribers |
| Tele2 | My services | VoWiFi | Depends on the phone model |
⚠️ Attention: Operators' mobile app interfaces are updated regularly. If you can't find the section you need, use the in-app search or contact support chat, as section names may change.
Using the engineering menu and codes
Advanced users can access hidden system settings through the engineering menu. This is a powerful diagnostic tool that allows you to manage radio module parameters. Be careful: changing unknown parameters may cause unstable phone operation.
To access the testing menu, open the Phone app and enter the special code. For devices Samsung a combination often works #0011# or #2263#However, access to these menus may be restricted by the manufacturer in new firmware versions.
In the engineering menu you need to look for sections related to Phone Information or Network SettingThere may be an option called "VoWiFi" or "IMS Status." Changing the status to "Disable" or "Deactivate" will forcefully disable the feature at the modem level. This method is useful if the default settings don't work.
*#0011# - Service Menu (Service Mode)
*#2263# - Setting network ranges and modes
*#9090# - USB configuration and diagnostics
It's worth noting that access to changing network parameters via codes is often blocked on global firmware versions. In this case, the system will simply display an error message or the code will not work. It is not recommended to use this method without a clear understanding of what you are doing.
What to do if the codes don't work?
If entering the code doesn't open the menu, the manufacturer has blocked this access in your software version. Try using third-party apps to access hidden menus, but be aware of the security risks.
Problems with connection quality and their solutions
If you've decided to disable Wi-Fi calling due to poor connection quality, it's worth analyzing the underlying cause. Often, the problem isn't with the technology itself, but with the router configuration or interference. Dual-band routers can cause interference if your phone constantly switches between 2.4 GHz and 5 GHz frequencies.
It's also worth checking whether power saving mode is enabled on your smartphone. Aggressive power saving can limit background network activity, leading to dropped calls when switching to Wi-Fi. Disabling battery optimization for the phone app may help.
In some cases, a simple network settings reset can help. This will reset all connection settings to factory defaults, deleting saved Wi-Fi passwords and Bluetooth settings, but it often resolves software conflicts. After the reset, the phone will re-register with the carrier's network.
- 📶 Check the router's signal strength in the place where you usually talk.
- 🔋 Turn off power saving mode during important calls.
- 🔄 Reset your network settings if the issue persists.
- 📱 Make sure your phone software is updated to the latest version.
Impact of roaming and tariffs
Cost becomes a critical issue when traveling abroad. VoWiFi technology allows you to save on roaming charges, as the call is considered to originate from your home network, even if you're physically located in another country. However, disabling this feature may be necessary to avoid double billing or identification complications.
Some carriers require geolocation to be enabled when using Wi-Fi Calling to confirm the subscriber is located outside the country. If you disable this feature, make sure you understand your carrier's incoming and outgoing call rates in your current region.
It's important to distinguish between Wi-Fi calls and calls made via messaging apps (WhatsApp, Telegram, Viber). Disabling VoWiFi in your phone's settings will not affect messaging apps. They will continue to work using any available connection and will be charged as data traffic.
⚠️ Attention: Roaming rules and VoWiFi service terms are subject to change. Before traveling abroad, be sure to check the current Wi-Fi calling rates with your carrier to avoid unexpected charges.
