Modern communications technologies strive to provide subscribers with a stable connection under any conditions, and one such feature is Wi-Fi Calling. This feature allows you to make voice calls and send text messages using your internet connection instead of a cell tower signal, which is especially useful in buildings with thick walls or in remote areas. However, this feature doesn't always work correctly: in some cases, it can interfere with roaming, quickly drain your battery, or simply be unnecessary if you already have a strong cellular signal.
Many users experience a situation where their phone automatically switches to Wi-Fi calling without their knowledge, resulting in unexpected audio quality issues or the inability to make an emergency call if the internet connection is weak. Disabling Wi-Fi Calling This is often a necessary step to normalize communication. In this article, we'll cover detailed steps for various operating systems and device models so you can easily manage this setting.
Before moving on to the settings, it is worth understanding that the menu interface may differ slightly depending on the version of the operating system and the manufacturer's shell. Android And iOS They're constantly updated, changing the order of the options, but the logic remains similar. If you can't find an exact match for an option name, look for synonyms like "Wi-Fi Calling" or "VoWiFi."
Why you should disable Wi-Fi calling
The main reason users look for a way to disable this feature is because their home internet connection is unstable. If your router is overloaded or your ISP is experiencing issues, voice traffic may be interrupted, creating a "robot" effect or even completely disconnecting. Unlike a video stream, which can be buffered, voice communication requires minimal latency, and Wi-Fi Calling here it often loses out to a stable 4G/LTE signal.
⚠️ Attention: In some regions or with certain carriers, Wi-Fi calls may be charged as international calls, even if you're at home. Be sure to check your plan's terms to avoid unexpected charges.
Another important aspect is power consumption. Constantly searching for and maintaining a connection to transmit voice traffic via Wi-Fi can lead to faster battery drain, especially on older smartphone models. Furthermore, when moving outside from the router's coverage area, the phone may not properly switch back to the cellular network, causing connection delays or dropped calls.
There are also situations where the feature conflicts with third-party calling apps such as Viber, Telegram or corporate Softphone-clients. In such cases, priority is given to the system function, which can block other services or create confusion when selecting the audio output device. Disabling this option restores the phone's default behavior, where priority is always given to the SIM card.
Instructions for iPhone (iOS) users
For owners of devices from Apple lucky with a single interface standard, so the process of disabling the function on iPhone The interface looks the same across most models, from iOS 10 to the latest versions. First, open the standard "Settings" app and go to the "Cellular" section. This is where you'll find all your voice communication settings.
The next step requires careful consideration, as the option may be hidden in a submenu. Select "Wi-Fi Calling" and toggle the switch to the off position. If you have two SIM cards in your phone, make sure you disable the feature for each card separately, as the settings may be duplicated or specific to each number.
In some cases, especially on carrier-bundled devices, the path may be slightly different. In these cases, you should look for "Cellular Settings" in the main Settings menu, rather than in the Phone app. Wi-Fi Calling On iOS, it is closely integrated with the security system, so after disabling it, the system may ask you to confirm the action or enter your Apple ID password if two-factor authentication is enabled.
☑️ Checking the Disabled Status on iPhone
It's worth noting that after disabling this feature, the "Wi-Fi" icon next to your carrier's name will disappear from the status bar. This indicates that all incoming and outgoing calls are now exclusively through the cellular network. If you're planning a trip abroad, we recommend taking this step first to avoid roaming charges.
Disabling the feature on Android: Samsung and Xiaomi
In the world Android The situation is somewhat more complicated due to the huge number of shells and interface modifications. On smartphones Samsung with shell One UI You need to go to "Settings," select "Connections," and find "Wi-Fi Calling." From there, simply move the slider. On devices Xiaomi with shell MIUI or HyperOS The way often lies through the "Phone" app: tap the three dots in the corner, select "Settings" and find the "Use Wi-Fi for calls" section.
It is important to understand that on some models Xiaomi In global versions, this feature may be hidden or renamed to "Wi-Fi Calling." If you can't find this option in the standard menu, try searching for "Wi-Fi" in Settings. The system will automatically suggest the appropriate shortcut. Disconnection On Android, this often requires a device reboot for changes to fully take effect, especially if the feature has been running for a long time.
Users Samsung You may also encounter a situation where your carrier blocks the ability to manually control this feature. In this case, the switch itself may not be available in the menu. A solution might be to install a profile SIM card from a different carrier for testing or reset the network settings, but these are extreme measures.
What to do if the item is not in the menu?
If you don't see the toggle, your carrier may not support this feature or have blocked it at the software level. Try updating your phone's software or contacting your carrier's support.
Setting up Huawei, Honor, and other brands
Devices from Huawei And Honor have their own interface specifics EMUI And Magic UIHere, controls are often located directly in the Quick Settings panel. Try swiping down twice from the top to open the full Quick Settings menu and look for a phone icon with a Wi-Fi symbol. If you don't see one, tap the edit button (usually a pencil or three dots) and add the "Wi-Fi Calling" widget to the panel. You can then quickly enable or disable it.
If you can't find the function through the notification shade, go to the deep menu: "Settings" → "Wireless & Networks" → "Wi-Fi Calling." On some models, this option may be located within the SIM card settings: "Mobile Network" → "SIM Card 1" → "Wi-Fi Calling." Interface may vary depending on the version of Android on which the manufacturer's shell is based.
For other brands such as Realme, Oppo or OnePlus, the logic remains similar: look for sections related to network and connections. Manufacturers often hide this option under "SIM cards and mobile network." Feel free to experiment with searching through the settings by entering the keywords "VoWiFi" or "Calls."
⚠️ Attention: After updating the firmware, network settings may reset to factory defaults. It is recommended to check the Wi-Fi Calling status after each major system update to ensure the feature does not re-enable automatically.
Comparison of impact on battery and connection quality
Many users are wondering how much Wi-Fi Calling Affects the battery life of the device compared to regular calls. The answer depends on the signal quality. If the cellular signal is weak (1-2 bars), the phone expends a significant amount of energy to boost it, and in this case, switching to Wi-Fi can actually extend battery life. However, with a stable 4G/5G signal, using an additional Wi-Fi module for voice transmission creates an unnecessary load.
Below is a table showing a rough comparison of operating parameters in different modes. The data is averaged and may vary depending on the smartphone model and operating conditions.
| Parameter | Regular call (4G/LTE) | Calling via Wi-Fi | Calling on weak signal |
|---|---|---|---|
| Battery consumption | Short | Average | Very tall |
| Sound Quality (HD) | High | Depends on the router | Low / Intermittent |
| Connection speed | Instant | Delay 1-3 sec | Long delay |
| Stability in motion | High | Low (cliffs) | Critical |
The table shows that in moving conditions (in public transport, outdoors), a standard cellular signal provides better stability. Wi-Fi Calling is designed primarily for static indoor use. If you frequently move between coverage areas of different networks, it's best to keep this feature disabled.
Solution: What to do if the feature won't turn off
Sometimes users encounter bugs where the function slider doesn't respond to taps or automatically resets to the "On" position. The first step should always be a full device restart. This clears temporary caches and resets network module errors. If this doesn't help, try removing the SIM card, wiping the contacts, and reinserting it.
The second method is resetting network settings. This won't delete your personal data, photos, or contacts, but it will reset all Wi-Fi, Bluetooth, and mobile data settings to factory defaults. The path to this feature is usually: "Settings" → "System" → "Reset" → "Reset Wi-Fi, mobile data, and Bluetooth settings." After this, you'll have to re-enter your Wi-Fi network passwords.
If the problem persists, it's possible there's a carrier profile conflict. In this case, updating your carrier profile (available in your SIM card settings) or contacting a mobile phone store to replace your SIM card with a newer one that supports modern encryption standards may help.
