Modern smartphones offer a variety of features to improve connection quality, and Wi-Fi calling is one of them. This technology allows you to make and receive calls in areas with poor cellular coverage using a wireless internet connection. However, in some situations, users may need to disable this feature, whether due to connection instability, increased data usage, or simply personal preference.
In this article, we'll take a detailed look at how to disable Wi-Fi calling on various phone models, explain how the technology works, and answer frequently asked questions. You'll learn why sound quality issues may occur and how to properly configure call settings for comfortable communication.
What is Wi-Fi calling and why should you disable it?
VoWiFi (Voice over Wi-Fi) technology allows voice data to be transmitted via the Internet protocol, bypassing standard GSM or LTE cellular communication channels. This is the solution This is especially relevant for rooms with thick walls, basements, or remote areas where base station signals are virtually nonexistent. Operators are implementing this feature to expand coverage without building new towers.
Despite the obvious benefits, there are reasons why a user may want to disable this feature. Smartphone interface The phone may not switch correctly between Wi-Fi and mobile networks during a call, resulting in dropped calls. Furthermore, when using public hotspots with low bandwidth, voice quality may be poor.
Another factor is cost control. Although many operators charge these minutes as regular ones, when roaming or using certain tariff plans, traffic may be charged separately. Some users also prefer to keep mobile network enabled only for emergency calls, relying on instant messengers for online communication.
⚠️ Note: Disabling Wi-Fi Calling does not block incoming calls via messaging apps (WhatsApp, Telegram, Viber). This setting only affects the default phone book and SIM card.
Preparation before changing settings
Before making any changes to system settings, it's recommended to perform a quick diagnostic of the current state. Ensure that the problem is truly with the VoWiFi function, and not a hardware issue with the speaker or microphone. Users often confuse poor connection quality due to a weak router signal with a software glitch.
Check if your operating system is up to date. In older versions Android or iOS The settings menu may be located differently or have different item names. Software updates often fix bugs related to switching between networks.
- 📱 Make sure your smartphone supports VoWiFi technology (usually models released after 2016).
- 📡 Check if the service is activated with your mobile operator (sometimes you need to activate it separately in your personal account).
- 🔋 Charge your device to at least 20% to prevent changes from being saved if it suddenly turns off.
If you plan to completely avoid using wireless networks for calls, it's also a good idea to check your network priority settings. In some cases, the phone tries to hold on to a weak Wi-Fi signal at all costs, ignoring a stable 4G connection.
☑️ Check before disconnecting
Instructions for Android smartphones
In the ecosystem Android The location of the settings may vary depending on the shell manufacturer and OS version. However, the general procedure remains similar for most devices, whether Samsung, Xiaomi, Huawei, or Pixel.
The standard route usually looks like this: open the Phone app, tap the three dots in the corner of the screen, and select Settings. Next, look for the "Wi-Fi Calling" section. On some models, this option is located in the General system settings.
Settings → Network & Internet → Mobile Network → Wi-Fi CallingOn devices Samsung Galaxy The path may vary: go to "Settings," select "Connections," then "Wi-Fi Calling," and toggle the switch to "Off." If you can't find this option, search for "Wi-Fi" in your settings.
| Phone brand | Path to the menu | Nuances |
|---|---|---|
| Samsung | Settings → Connections → Wi-Fi Calling | It may be called "Wi-Fi Calling" |
| Xiaomi / Redmi | Settings → SIM cards & mobile networks → Wi-Fi calling | Not available on all models |
| Huawei / Honor | Settings → Wireless & networks → More → Wi-Fi calling | Depends on the EMUI version |
| Google Pixel | Settings → Network & Internet → Mobile Network → Wi-Fi Calling | Clean Android interface |
How to disable this feature on iPhone (iOS)
For product owners Apple Finding the right setting is easier, as the iOS interface is unified. The function is called "Wi-Fi Calling" and is controlled through the cellular menu. It's important to note that on iPhone, this setting often syncs with other Apple devices if the corresponding option is enabled.
To disable it, go to "Settings" and select "Cellular." Find "Wi-Fi Calling" and toggle the slider to the off position. If you have two SIM cards (a physical one and an eSIM), you'll need to check the setting for each number separately.
Sometimes users encounter a situation where calls still go over the internet after disabling Wi-Fi on their iPhone. This may be due to the "See Other Devices" feature. When enabled, your iPad or Mac can receive calls over the internet even if Wi-Fi is turned off on the phone itself.
- 🍏 Open Settings → Cellular.
- 📞 Select "Wi-Fi Calling" and turn off the toggle switch.
- 🔄 Check the "On other devices" section and disable "Allow calls" if you want to disable it completely.
⚠️ Note: On iOS, disabling this feature may cause the "Wi-Fi" icon next to your carrier name to disappear from the status bar, which is normal system behavior.
Solving problems with double calls and quality
One of the most annoying problems when using VoWiFi is the "double ring" effect, where the phone rings simultaneously over the cellular network and over the internet. This happens because smartphone cannot quickly determine the priority communication channel.
To avoid this, some carriers recommend completely disabling Wi-Fi during an incoming call if you're in a strong cellular coverage area. However, a better solution is to set a priority. The "Wi-Fi Calling" menu often includes a "Network Preference" option.
Select "Cellular preferred." This option will use your phone's cellular data even if Wi-Fi is available, and will only switch to wireless when there's no signal at all. This helps conserve battery life and avoid routing conflicts.
Impact of settings on battery and traffic
Many users wonder whether active VoWiFi mode affects the battery life of their device. Technically, maintaining a constant connection for voice calls over Wi-Fi can consume more power than waiting for a signal in standby mode, especially if the router is far away and the phone increases its transmit power.
On the other hand, in conditions of extremely weak cellular signal (1-2 bars), the phone spends a colossal amount of energy searching for a base station. In such situations Wi-Fi CallingOn the contrary, it extends battery life because the Wi-Fi module operates in a more energy-efficient mode.
Regarding traffic, one minute of high-quality voice calls (HD Voice) consumes approximately 1 MB of data. This isn't a significant amount for modern plans, but it's worth considering if you have a limited connection (such as tethering from a phone).
⚠️ Note: Mobile app interfaces and system settings may be updated. If the described paths don't match your screen, use the search in your phone's settings.
Frequently Asked Questions (FAQ)
Do carriers charge extra for Wi-Fi calls?
In most cases, you'll be charged the same as your regular plan minutes. However, if you're roaming internationally, the rules may differ: incoming Wi-Fi calls may be free, while outgoing calls may be charged at the same rate as domestic calls. Always check with your carrier before traveling.
Is it possible to call emergency services (112, 911) via Wi-Fi?
Technically, this is possible, but it's not recommended to rely solely on this feature in critical situations. When calling over Wi-Fi, the operator may not receive your exact location coordinates, as an IP address isn't always linked to a physical address. In emergency situations, it's better to use a direct cellular connection.
Why did incoming calls disappear after disabling the function?
This is a rare network registration bug. Try turning Airplane Mode on and off or restarting your phone. The device will re-register with your carrier's network without the VoWiFi protocol.
Does this function work if the router distributes the Internet from the phone?
No, most carriers block Wi-Fi calls if the phone itself is sharing the internet (tethering). In this case, the channel is busy transmitting data, and voice traffic may not be prioritized or blocked.
Do I need to reactivate the service with my operator after resetting the settings?
The service is usually tied to the SIM card on the network side and doesn't require reactivation. However, the settings in the phone menu will be reset, and you'll have to switch the switch back to the "On" position if you want to restore the feature.
