Modern smartphones running the operating system Android have a wide range of features that allow you to make voice calls even without a cellular signal, using a wireless network. This technology, known as Wi-Fi CallingWhile mobile broadband provides stable connectivity in poor reception areas, not all users require it all the time. In some situations, a standard mobile connection is preferable for a variety of technical and economic reasons.
Users often need to force their device to switch to a mobile network to avoid issues with sound quality or latency. The process for disabling this feature may vary depending on your device model and the firmware version installed. In this article, we'll cover all the available methods. disable calls over WiFi, and we will explain in which cases this really needs to be done.
It's worth noting that this option is directly accessible to the user, but sometimes hidden deep within system settings. We'll cover the standard menu paths specific to different manufacturers and also touch on SIM card issues. Understanding how this feature works will help you better manage your smartphone's performance and resource consumption.
Why might you need to disable the call function?
The main reason gadget owners look for a way to disable WiFi calls is the instability of wireless connections in crowded areas. In shopping malls, train stations, or office buildings, the network can be overloaded, leading to interruptions in voice quality and digital artifacts during calls. In such conditions, mobile network often provides clearer sound and lower data transfer latency.
Another important factor is increased battery consumption. Constantly searching for and maintaining a connection to an access point for voice traffic can significantly accelerate the device's battery life, especially if the Wi-Fi signal is weak. Furthermore, some users prefer to use VoIP apps (e.g., Telegram or Viber) for communication via the Internet, leaving a regular phone number exclusively for mobile communications, so as not to confuse contacts.
⚠️ Attention: If you are in an area with no cellular signal, disabling this feature will prevent you from making or receiving regular phone calls. Make sure you have an alternative method of communication or are within the carrier's coverage area.
It's also worth mentioning situations where the telecom operator doesn't fully support VoWiFi (Voice over WiFi) technology or charges for these minutes separately. In this case, the data savings may be illusory, and the connection quality may be unsatisfactory. Disabling this option forces calls to be routed through standard GSM or LTE channels, which sometimes resolves the issue of dropped calls.
Where to find settings in the standard Android interface
In most modern smartphones, the function control Wi-Fi Calling The switch has been moved to the main settings menu, making it easier to find. However, the path to it may vary slightly depending on the operating system version and the manufacturer's shell. The standard procedure usually begins with opening the main settings menu and finding the section related to network connections.
Most often, the item you're looking for is located within the "Connections" or "Network and Internet" tab. This is where all the settings related to SIM cards and mobile networks are located. If you're using a clean Android (for example, on smartphones Google Pixel or Motorola, Nokia), the menu structure will be as logical and clear as possible, without unnecessary branches.
For devices with shells from other manufacturers, such as Samsung or Xiaomi, item names can be adapted to suit the corporate style. For example, in some versions One UI Samsung's settings may be hidden within the Phone app menu, rather than in the general system settings. This is an important detail that's often overlooked by users looking for the switch in the standard location.
It's important to understand that the presence of the switch itself depends not only on the phone itself, but also on the support of the feature by your SIM card and carrier. If the option is completely missing, it's possible that your tariff plan or service provider doesn't support the technology. VoWiFi in your region. In this case, there's no point in looking for a button to disable it, as it's inactive by default.
Instructions for various smartphone manufacturers
Because the interface Android It's heavily modified by manufacturers; let's look at specific approaches for the most popular brands. Smartphone owner Samsung must go to Settings → Connections → Wi-Fi CallingHere you can not only disable the feature, but also select the network priority: "Mobile network preferred" or "Wi-Fi network preferred."
On devices Xiaomi, Redmi And Poco with shell MIUI or HyperOS the path often looks like this: Settings → SIM cards & mobile networks → Wi-Fi calling., that on some global firmware versions this item may be hidden if the telecom operator has not certified the device to work in specific regions.
For smartphones Google Pixel and other devices with a clean interface, the algorithm is as follows: Settings → Network & Internet → Mobile Network → Wi-Fi CallingThe interface here is minimalist, and the switch is immediately accessible, eliminating the need to navigate through additional submenus. This simplifies the task for those who frequently change network settings.
☑️ Check before disconnecting
Devices from Huawei And Honor (with or without Google services) also have their own peculiarities. Usually the path goes through Settings → Wireless & networks → Mobile networks → Wi-Fi callingIf you don't see this option, try searching through your settings and searching for "Wi-Fi Calling" or "VoWiFi."
| Smartphone brand | Path to settings | Interface nuances |
|---|---|---|
| Samsung | Settings → Connections | There is a choice of network priority |
| Xiaomi / Redmi | Settings → SIM cards and mobile networks | May be absent on global firmware versions |
| Google Pixel | Settings → Network & Internet | Minimalistic interface, quick access |
| Huawei / Honor | Settings → Wireless & Networks | Searching through the menu bar is often required |
Control via the operator's application
In some cases, the settings on the phone itself may be locked or hidden by the carrier. Then the only way to manage the service Wi-Fi Calling Your provider's proprietary app (for example, "My MTS," "My Beeline," "My Tele2," or "My Megafon") becomes your service. This is a common practice when control over the service is transferred to the operator.
To disable this feature through the app, log in to your account using your phone number or password. Then, find the section for additional services or communication settings. There may be a switch there to enable or disable voice calling over the internet.
⚠️ Attention: Telecom operators' mobile app interfaces are frequently updated. If you can't find the switch you need, use the in-app search or contact support chat, as the menu location may change.
The advantage of managing your settings through the operator's app is that changes are applied network-wide. This means that even if you reset your phone or reinstall your SIM card, your preferences will remain until you change them in your account. This is especially convenient for users who want to centrally manage services for their entire family.
What should I do if the app doesn't show settings?
Sometimes settings are hidden for certain tariff plans. Try logging into your account through a computer browser—the web version often has an extended service settings menu that isn't available in the mobile app.
Problems with connection quality and duplicated calls
One of the most annoying problems when using Wi-Fi Calling Call duplication is a common problem. This occurs when, when an incoming call occurs, both the regular phone interface and the operator app or system dialer begin ringing simultaneously, creating chaos. Disabling this feature often solves this problem, returning the device to its default behavior.
Furthermore, the voice encoding quality over WiFi may be lower than over a HD Voice (VoLTE) cellular network. If you notice a delay in hearing you or your voice sounds robotic, this is a clear sign that your current internet connection can't handle the real-time data flow. In such cases, switching to LTE/4G improves speech intelligibility.
It's also worth considering the priority conflict. The smartphone may attempt to connect to a Wi-Fi call even with a very weak router signal, ignoring the excellent signal from a nearby cell tower. Manually disabling this option forces the phone to ignore Wi-Fi for voice calls, which improves connection reliability in some scenarios.
Impact on battery life and data security
Using the internet for voice calls requires Wi-Fi to be constantly active, even when the screen is off. This means the phone is less able to "sleep" in standby mode, which negatively impacts battery life. If you're critical to your smartphone lasting all day without recharging, disabling background network activity, including VoWiFi, can add 10-15% to battery life.
From a security standpoint, calls over public Wi-Fi networks (in cafes, airports, and hotels) can theoretically be less secure than through cellular networks, although modern encryption protocols (IPSec) minimize this risk. However, for confidential conversations, using open networks always carries the potential risk of traffic interception unless additional security measures, such as a VPN, are used.
However, if you're at home with a password-protected router, the risks are minimal. The main impact here is still on resource consumption. Constantly switching between WiFi and cellular networks in search of a better signal also puts stress on the device's modem, which indirectly affects its heating and power consumption.
The Myth of Safety
Many people believe that calls made over WiFi are completely anonymous. This isn't true. The mobile operator still sees the connection and its duration, even if the traffic is transmitted over the internet. Only special messaging apps with end-to-end encryption provide complete anonymity, not a standard phone book.
Frequently Asked Questions (FAQ)
Does disabling WiFi calling affect my call charges?
No, if you use your carrier's standard Wi-Fi Calling feature, minutes are usually charged according to your primary plan, just like regular voice calls. However, if you disable this feature and are abroad without roaming, you won't be able to receive calls at all. Rates in your home region generally remain the same.
Will the setting be reset after updating the Android system?
In most cases, user settings, including disabling Wi-Fi Calling, are retained after updating the operating system. However, after major updates (for example, upgrading from Android 13 to 14) or a factory reset, the feature may revert to its default state, which is often enabled. It is recommended to check your settings after major updates.
Is it possible to disable Wi-Fi Calling for only one SIM card?
Yes, if your smartphone supports two SIM cards, the settings are usually applied individually to each slot. By going to the settings for a specific SIM card (Settings → SIM cards), you can select the one you need and disable the WiFi calling feature only for it, leaving the second one active.
Why did all calls disappear after disabling the feature?
This can happen if there's no cellular signal at your current location, and your phone relied solely on WiFi to connect to the outside world. In this situation, you'll need to move to an area with strong mobile coverage or temporarily re-enable the feature.
