Modern smartphones offer many features to improve the quality of communication, and one of these options is Wi-Fi CallingThis technology allows voice calls to be made over an internet connection when the cellular signal is weak or absent. However, using the Internet Protocol for voice transmission is not always convenient or beneficial for the user, especially in unstable roaming conditions or with specific data plans.
Many subscribers are faced with a situation where the phone automatically switches to Wi-Fi Calling without the owner's knowledge, which can lead to unexpected charges or degraded sound quality. Understanding how to manage this feature is becoming a critical skill for any smartphone owner. In this article, we'll take a detailed look at How to turn off Wi-Fi calling on various operating systems so you can have full control over your device.
Disabling this feature may be necessary not only for cost savings but also to resolve technical issues, such as dropped calls when switching between networks. We'll explore the nuances of this technology across different carriers and equipment manufacturers so you can be confident in your actions. Let's take a closer look at the mechanisms for managing voice communications in the digital age.
What is Wi-Fi Calling and why should you disable it?
Technology VoWiFi (Voice over Wi-Fi) enables voice traffic to be transmitted over a wireless network using the same protocol as IP telephony. This solution was developed to improve coverage in buildings with thick walls or in remote areas where cell tower signals are virtually nonexistent. The smartphone automatically detects a weak signal and routes the call through an available access point, ensuring uninterrupted communication.
Despite the obvious benefits, there are scenarios where the user needs to disable this option. For example, when roaming, some operators may charge incoming and outgoing Wi-Fi calls as regular international calls unless a special service package is activated. Furthermore, connection quality directly depends on the channel's bandwidth and the number of connected devices.
Users often confuse this feature with instant messengers or video calls, but Wi-Fi Calling This feature operates at the system level and uses the standard dialer. Disabling this feature returns the phone to a cellular-only network search mode, which can be useful for diagnosing connection issues or forcing a switch to a more stable, albeit slow, 2G/3G signal in an emergency.
⚠️ Attention: Before disabling this feature, make sure you have a strong mobile signal in the area. If you're in a "no-call" zone without Wi-Fi access, you may become unavailable for incoming calls.
Disable Wi-Fi Calling on iPhone (iOS)
For smartphone owners Apple It's important to know that managing this feature on iOS has its own specifics, depending on the operating system version and carrier profile. The deactivation process is fairly simple, but requires attention, as the settings may be hidden in different submenus depending on the device model. The standard method is through the main system settings.
To get started, open the "Settings" app and go to the "Phone" section. This is where you'll find the main voice settings. If your carrier supports this technology, you'll see "Wi-Fi Calling," which you can select to drill down to more detailed settings. In some regions or with certain providers, this option may have a different name or be combined with the cellular settings.
- 📱 Open "Settings" and select "Cellular" or "Phone".
- 📶 Find the "Wi-Fi Calling" option and toggle the switch to the off position.
- 🔄 If you have two SIM cards, make sure you disable the feature for the desired number by selecting it from the list.
- 📞 Check the status in the "Control Center" by adding the corresponding widget there for quick access.
It's important to note that on some dual SIM devices, settings may apply globally or individually for each number. iOS interface This may change slightly with the release of new updates, so if you don't find the item right away, check the "General" section or use the settings search by entering the keyword "Wi-Fi".
☑️ Check before disabling on iPhone
Android Setup: Samsung, Xiaomi, and Other Brands
World Android The app comes in a huge variety of skins, so the steps to disable the feature may vary from model to model. However, the general logic remains the same: the settings are located in the network management menu or in the settings of the Phone app itself. On smartphones Samsung With the One UI shell, the path usually lies through "Settings" → "Connections" → "Wi-Fi Calling".
Devices from Xiaomi (MIUI/HyperOS) often hide this option deeper. You may need to go to the SIM cards and mobile networks settings, select a specific SIM card, and find the switch there. In stock Android (for example, on Pixel or Motorola) the settings are often placed in a separate "Network and Internet" menu, where call control is grouped by SIM card for user convenience.
If you can't find the switch using standard methods, you can use the engineering menu or search within the settings. Enter "Wi-Fi" or "Calls" in the settings search bar, and the system will automatically suggest the appropriate option. This is especially important for devices with custom firmware, where standard navigation may be disrupted.
| Brand / Shell | Path to the menu | Peculiarities |
|---|---|---|
| Samsung (One UI) | Settings → Connections | Separate switch for each SIM |
| Xiaomi (MIUI) | Settings → SIM cards → Selected SIM | It may be called "Wi-Fi Calling" |
| Google Pixel | Settings → Network & Internet | Google Dialer integration |
| Huawei (EMUI) | Settings → Wireless & Networks | Often hidden in advanced settings |
⚠️ Attention: On some Android models, the switch may be blocked by your carrier. In this case, changing the settings is only possible by contacting support or using a special USSD code, if available.
What to do if the item is not in the menu?
If you can't find the switch in the standard menu, it may mean your carrier doesn't support VoWiFi technology or hasn't transferred the settings profile to your phone. Try updating your network settings or resetting them to factory defaults. Also, check if the feature is blocked by your plan. In rare cases, installing a special operator certificate may be required.
Control via telecom operator applications
Modern telecom companies strive to transfer as much service management as possible to their mobile apps. This allows subscribers to control tariffs, activate options, and, of course, manage additional services such as Wi-Fi CallingIf you can't find the required switch in your phone's settings, there's a good chance that control has been completely transferred to your carrier.
Open your carrier's personal app (e.g., My MTS, Megafon, Beeline, Tele2, or Tinkoff Mobile). Under "Services" or "Communication Settings," you'll often find an option called "Wi-Fi Calling." Here, you can not only disable the feature but also view usage statistics if your rate is based on minutes.
- 📲 Log in to the operator's app using your phone number.
- 📡 Go to the "My number" or "Services and options" section.
- 🔌 Find the block related to voice communication or internet calls.
- 🚫 Click the "Disable" button or move the toggle switch to the "Off" position.
The advantage of managing your account through the operator's app is that changes take effect immediately and sync across all devices linked to the number. This is especially convenient if you frequently change smartphones or use a SIM-enabled tablet, as the settings are transferred along with the subscriber profile, rather than being stored solely in the phone's memory.
Impact of roaming and call pricing
The issue of saving money becomes especially pressing when traveling abroad. Many users mistakenly believe that connecting to hotel Wi-Fi automatically makes calls free if it is enabled. Wi-Fi CallingHowever, roaming conditions dictate their own rules, and this carries the risk of incurring a huge communication bill.
In most cases, if you're abroad and make a call via Wi-Fi Calling, your carrier may treat it as a regular call from your home country or the country your SIM card is registered in, depending on your plan. Some carriers do offer free incoming and outgoing calls over Wi-Fi while roaming, but this should always be specified in the terms of your specific plan.
To avoid unpleasant surprises, be sure to check with your provider about VoWiFi roaming pricing before your trip. It's best to be on the safe side and disable the feature when using messaging apps (WhatsApp, Telegram, FaceTime) for internet calls, as they only use data traffic, which is often free at hotels.
⚠️ Attention: Roaming and pricing rules are subject to change by operators unilaterally. Always check the latest terms and conditions in your personal account or the official app before traveling to avoid unexpected charges.
Communication quality problems and diagnostics
Sometimes users decide to disable this feature due to poor connection quality: robotic voices, delays, or dropped calls. This often happens when the home Wi-Fi is overloaded with other devices (4K TVs, gaming consoles, torrenting), and there simply isn't enough bandwidth for voice traffic.
Diagnosing the problem begins with checking the internet speed. If the ping is high or the speed is unstable, the phone will constantly try to switch between Wi-Fi and cellular, causing characteristic clicking and interruptions. In this situation, disconnecting VoWiFi and switching to a stable, albeit slower 4G/LTE signal can significantly improve speech intelligibility.
It's also worth considering that some routers have traffic prioritization (QoS) settings. If your router is old or configured incorrectly, it may not prioritize voice packets, sending them to the end of the queue. In this case, even a fast internet connection won't prevent connection problems, and the only solution is to use a cellular network.
- 📉 Check your internet speed at speedtest.net while making a call.
- 📡 Make sure that the Wi-Fi signal in the place where you are talking is strong (at least 2-3 bars).
- 🔄 Try rebooting your router to clear any cache errors.
- 📞 Make a test call after disabling the feature to compare the quality.
Why does the call disconnect when I leave the house?
This is a classic "handing over" problem. The phone doesn't have time to quickly and seamlessly switch the call from Wi-Fi to the cellular network. If this happens frequently, it might be a good idea to turn off the feature or be in a strong cellular coverage area before starting an important call.
