Modern smartphones Samsung They are equipped with a variety of features to improve call quality, one of which is VoWiFi technology. This feature allows for calls over a wireless network, which is especially useful in areas with poor cellular coverage. However, this feature doesn't always work correctly, and users often find themselves forced to disable it.
The reasons for such actions can vary widely, from a simple desire to save data to solving problems with an unstable connection or rapid battery drain. In some situations, the phone may become stuck on a weak Wi-Fi signal instead of switching to a stable mobile network, leading to interrupted calls. Understanding that How to disable Wi-Fi calling on a Samsung phone, is becoming an essential skill for any smartphone owner.
In this article, we'll cover all the available methods for disabling this feature in detail. You'll learn where to find the necessary switches in different versions of One UI, what to do if the standard menu isn't working, and what nuances to consider when setting up connectivity. This guide is designed to be useful for both beginners and experienced users looking to optimize their device.
Why might you need to disable the VoWiFi feature?
Voice over Wi-Fi technology is designed to improve call quality, but in practice, its implementation isn't always perfect. Users often notice that when switching between coverage areas (for example, going outside), the call drops abruptly. This happens because the smartphone Samsung The Wi-Fi connection fails to transfer to the cell tower in a timely manner. In such cases, forcibly disabling the feature helps preserve the conversation.
Another common problem is increased power consumption. Constantly searching for and maintaining a stable connection for voice transmission can significantly strain the processor and radio module. If you're in a location with good mobile network coverage, using Wi-Fi for calls becomes an unnecessary drain on resources. Deactivating VoWiFi in this situation, it extends the battery life of the device.
It's also worth mentioning compatibility with some routers and corporate network security settings. Certain encryption protocols can interfere with voice packet transmission, causing echo, delays, or complete loss of audio. In office networks, administrators sometimes block the ports required for this technology, rendering it useless.
⚠️ Important: Before changing your communication settings, make sure your tariff plan supports voice calls over a mobile network, as after disabling Wi-Fi, calls will be charged according to your operator's standard terms.
The settings interface may vary depending on your operating system version and device model. If you can't find the exact item described, try searching through the settings or updating your software to the latest version.
The standard way to disable it is through the settings menu.
The easiest and most secure method for managing VoWiFi is built into the standard Android interface. On smartphones Samsung With One UI, this process is incredibly simplified and takes just a few seconds. You don't need to install third-party apps or have root privileges.
To get started, unlock your device and find the "Settings" icon on the home screen or in the app drawer. It usually looks like a gear. Once you've entered the menu, scroll down to the "Connections" section. This is where you'll find all the settings related to network, Bluetooth, and mobile data.
Under the "Connections" section, find "Mobile Network." Tapping it will take you to the expanded SIM card management menu. Here, among other options, you'll find the "Wi-Fi Calling" toggle. If it's active (the slider is blue or green), simply tap it to turn it off.
It's important to note that on some dual-SIM models, settings may apply individually to each SIM card. Make sure you've selected the SIM card you want to change the settings for. This is visually indicated at the top of the screen or by selecting the active SIM card before entering the menu.
Control via the quick action bar
For those who need to frequently switch connection modes, there's a faster way. The quick action bar lets you manage the VoWiFi function without diving deep into the settings menu. This is especially convenient when you need to quickly respond to changing signal conditions.
To access the panel, swipe down from the top of the screen. On some models Samsung Double-swipe to expand the full list of available widgets. Among the icons, look for the one labeled "Wi-Fi Calling" or the one with a phone handset and a Wi-Fi icon.

☑️ Check before disconnecting
Using the quick menu saves time, but it's worth remembering that the status bar icon's visual appearance may vary across firmware versions. Sometimes it's just a "W" next to the connection indicator, while other times it's a full-fledged icon.
Dual SIM settings
Owners of dual-SIM devices face additional configuration nuances. Smartphones Samsung Allows you to flexibly configure connection parameters for each card separately, giving you more control over costs and connection quality.
When you access the "Mobile Network" menu, the system may prompt you to select which SIM card you want to change settings for. If you don't see this option immediately, look for the toggle at the top of the screen or in the "SIM Manager" list. Here you can set the priority card for calls and data.
It's recommended to disable VoWiFi on the card used primarily for voice calls if the mobile network is stable. For the second card, used primarily for internet, you can leave it enabled if you frequently travel to areas with poor coverage.
| Parameter | SIM card 1 (Primary) | SIM card 2 (Additional) |
|---|---|---|
| Network mode | 5G/LTE/3G/2G | 5G/LTE/3G/2G |
| Wi-Fi Calling | Off | Included |
| data roaming | Off | Off |
| Mobile data | Included | Off |
This configuration optimizes the device's performance by taking advantage of each network's advantages. However, be careful not to conflict with each other, especially in standby mode.
Troubleshooting if the option cannot be disabled
Sometimes users encounter a situation where the switch in the settings menu is grayed out or the feature re-enables itself. This may indicate carrier restrictions or firmware errors.
First, check whether your carrier supports this feature and whether it's enabled in your plan. Some providers block manual VoWiFi management, imposing their own terms. In this case, contacting your carrier's technical support may help.
If the problem is software related, try resetting your network settings. Go to Settings → General Settings → Reset → Reset Network SettingsPlease note that this action will delete saved Wi-Fi passwords and Bluetooth settings, but will not affect any personal data.
⚠️ Caution: Resetting network settings is a drastic measure and should only be used if other methods have failed. Be sure to save important Wi-Fi passwords before performing this procedure.
What to do if resetting doesn't help?
If resetting network settings doesn't resolve the issue, there may be a conflicting app or a firmware update is needed. Try starting your phone in Safe Mode to rule out any interference from third-party software. To do this, press and hold the Power button, then tap and hold the "Power off" icon on the screen until the prompt appears.
The impact of flight mode and power saving
Airplane mode completely disables all wireless modules, including Wi-Fi and cellular communications. However, in modern smartphones Samsung It's possible to leave Wi-Fi on even when airplane mode is activated. In this case, VoWiFi may continue to function if it was previously enabled.
Power saving mode can also affect the behavior of network modules. If background app activity is severely restricted, the system may forcibly disable VoWiFi to conserve battery life, or, conversely, leave it active if it's considered a priority communication function.
Check your battery optimization settings. Go to Settings → Device Maintenance → BatteryMake sure that the phone app and system communication services are not set to overly aggressive limits that may cause instability.
