Modern smartphones offer many features to improve communication quality, and one of them is the technology Wi-Fi CallingIt allows you to make voice calls over a wireless network, which is especially useful in areas with poor cellular signal. However, not all users find this default option convenient, as it can cause unexpected network switching or echo during calls.
Many device owners find it necessary to disable this feature so their phone uses only the carrier's cellular network. This may be due to pricing, roaming restrictions, or simply personal preferences regarding connection stability. In this article, we'll detail how to find and disable this setting on various platforms.
The disabling process doesn't require any special technical knowledge, but the path to the required switch may differ depending on your gadget model and operating system version. We'll cover the current interfaces for iOS And Android, and we'll also touch on settings from telecom operators, which sometimes block changes to device parameters.
Why you should disable internet calls
The main reason for refusing to use VoWiFi (Voice over Wi-Fi) often causes smartphones to behave erratically when switching between wireless networks. When you leave the router's coverage area, the phone should immediately hand over the connection to the cell tower, but in reality, this process sometimes takes several seconds, during which the other person's voice may be interrupted or the connection may be lost entirely.
Another important aspect is the quality of the internet connection itself. If your home router is overloaded with torrents or 4K video streaming, voice traffic may be given low priority, resulting in a tinny voice quality and delays. In such cases, Forcing the use of a cellular network, even with 2-3 signal bars, often produces clearer sound, than fast but congested Wi-Fi.
⚠️ Attention: Some mobile phone plans may charge Wi-Fi calls as regular minutes, but international roaming rules may differ. Always check with your provider before traveling abroad.
There are also situations where the feature doesn't work correctly due to conflicts with VPN services or corporate network security settings. If you notice that incoming calls only connect when the wireless network is turned off, or vice versa, the problem lies in how your device prioritizes communication channels.
Disabling the feature on Apple iPhone devices
Owners of smartphones from Apple have the easiest time managing this option, since the settings interface in iOS It's standardized and independent of the shell manufacturer. First, you need to make sure your carrier supports the technology and that it's activated on your SIM card; otherwise, you won't see the menu item.
To find the toggle, open the default Settings app and go to the Cellular section. Find "Wi-Fi Calling" and toggle the toggle to the off position. If you have two SIM cards installed in your phone, make sure you've changed the settings for the correct number, as these settings may be specific to each line.
- 📱 Open Settings and select Cellular.
- 🔘 Find "Wi-Fi Calling" in the list of options.
- 🚫 Turn the switch to the “Off” position (gray color).
- 📞 If necessary, repeat the action for the second SIM card.
After completing these steps, the "Wi-Fi" icon next to the operator name will disappear from the status bar, indicating a switch to the standard voice protocol. If the menu item is missing, your plan may not support this technology or your operator profile may need to be updated.
What to do if the switch is gray?
If the slider is grayed out and inactive, this means the setting is blocked by your carrier profile. In this case, you should contact your mobile carrier's support team to deactivate the service through your personal account or by phone.
Wi-Fi Calling Settings on Android Smartphones
In the world Android The situation is a bit more complicated due to the vast number of different interfaces used by electronics manufacturers. The path to the settings may have different names, but the logic remains the same: you need to find the section responsible for network connections or phone calls. Most often, the desired item is hidden in the "Connections" or "Network and Internet" menu.
On devices Samsung And Xiaomi The algorithm of actions may differ. For example, on Samsung devices, the path through the "Phone" app is often used, where the three-dot menu hides additional settings. On a "clean" Android (Pixel, Motorola) everything is in the general system settings.
Let's consider a universal search algorithm that works in most cases:
- Go to "Settings" on your device.
- Select the Connections, Network & Internet, or Mobile Network section.
- Find the line "Wi-Fi Calling" and turn off the toggle switch.
- If the item is not in the general settings, open the Phone app, tap the three dots (menu) and select Settings.
☑️ Check before disconnecting
Some manufacturers, such as Huawei or HonorThis option may be hidden deep in the "Call Management" menu. If you can't find the setting, search for "Wi-Fi" or "Calls" in the settings menu. This is the fastest way to get to the desired section, avoiding long menu navigation.
Specifics of disabling on different phone models
Differences in software dictate their own navigation rules. Below is a table to help you navigate the settings paths for popular brands. Keep in mind that the names of the options may change slightly after an operating system update.
| Brand / Model | Path to setup | Interface nuances |
|---|---|---|
| Samsung Galaxy | Settings → Connections → Wi-Fi Calling | May require confirmation via SMS |
| Xiaomi / Redmi | Settings → SIM cards and mobile networks → Wi-Fi calling | Separate switch for each SIM |
| Google Pixel | Settings → Network & Internet → Mobile network → Advanced | Google Dialer integration |
| iPhone (iOS) | Settings → Cellular → Wi-Fi Calling | Single interface for all models |
On devices Xiaomi With MIUI or HyperOS, it's common for settings to be reset after a firmware update. Therefore, if you've previously disabled this feature, it's worth rechecking its status. Also, on some Chinese smartphones, this option may be hidden or replaced by similar features from third-party apps.
For owners Samsung It is important to know that disabling this feature may affect the operation of the video calling feature. VoLTE, if they are integrated into a single system by the operator. However, in most regions, these technologies operate independently.
Managing the service through a telecom operator
Sometimes the phone's settings don't produce the desired result because the service is activated by the provider. In this case, the phone will persistently prompt you to use Wi-Fi for calls or automatically switch to it. The solution is to deactivate the service through your account or via USSD commands.
The largest operators (the Big Four in Russia and major players in the CIS) offer the ability to manage services through their mobile apps. Go to the "Services" or "Price" section, find the "Additional Features" section, and disable the "Wi-Fi Calling" option. This action takes precedence over the settings in your smartphone's menu.
An alternative method is to use USSD codes. While they may change, standard commands often work for years. For example, to disable the service, codes like 111.. or *105#It's best to find the exact code on your operator's official website in the help section, as it's specific to each plan.
⚠️ Attention: Changes to settings made through your carrier may not take effect immediately. In some cases, you may need to reboot your device or wait up to 24 hours for the network profile to fully update.
If you're roaming, disabling this service through your carrier can be critical to saving money, even if it's blocked on your phone. Some carriers charge incoming Wi-Fi calls while roaming unless a special rate is set.
Troubleshooting and Common Mistakes
Users often encounter situations where, despite seemingly having configured everything correctly, their phone continues to behave strangely. For example, the handset icon with the Wi-Fi symbol appears and disappears. This may indicate that the "Call Transfer to Other Devices" feature (applicable to Apple and Samsung devices) is enabled, duplicating the call to a tablet or laptop.
Another common mistake is the confusion between Wi-Fi Calling and messengers. Disabling the system function will not prevent you from making calls through WhatsApp, Telegram or ViberThese apps use the internet directly and don't rely on your phone's system settings. To prevent them from disturbing you, you need to configure notifications within the apps themselves.
It's also worth checking whether Do Not Disturb or Airplane Mode is enabled while Wi-Fi is on. In some cases, users inadvertently enable Airplane Mode while leaving Wi-Fi on, wondering why regular calls aren't connecting while the internet works.
Impact of outage on call quality and battery
Disabling voice over Wi-Fi can improve your device's battery life. Constantly searching for and maintaining a stable connection for voice traffic, especially when the router's signal is weak, forces the phone's modem to work in overdrive, which drains the battery faster.
On the other hand, if your home's cellular signal is very weak (1-2 bars) and your Wi-Fi is strong, disabling this feature will degrade the connection quality. In such cases, the phone will use more energy to boost the cell tower signal. Therefore, the decision to disable this feature should be based on the specific signal conditions in your location.
It's also important to note the impact on audio quality. Cellular networks, especially 4G/LTE-enabled ones, HD Voice, often provide more stable and high-quality sound than overloaded home networks. If you hear an echo or a robotic voice, try disabling Wi-Fi Calling—this may solve the problem.
Is it safe to disable this feature completely?
Yes, it's completely safe for your device and SIM card. You're simply switching the channel priority. The only risk is reduced reception if your home's cellular network is poor and your Wi-Fi is excellent.
Can a carrier charge for using Wi-Fi Calling?
In most cases, domestic calls are charged according to your base rate (package minutes). However, international roaming rules may differ, so be sure to check with your provider before traveling.
What should I do if my incoming messages disappear after disabling?
Try restarting your phone. If the problem persists, check if call forwarding or Do Not Disturb mode is enabled. Also, make sure the SIM card is correctly detected by the network.
Does this feature work without internet on the phone?
No, Wi-Fi Calling requires an active internet connection. If the router's internet connection is disabled, the feature won't work, even if it's enabled in the settings.
