Modern smartphones of the brand Xiaomi, working on the shell MIUI or new HyperOS, have a wide range of functionality that is not always needed by every user. One of these functions is Wi-Fi Calling, which allows you to make calls over the internet in areas with poor cellular coverage. However, in some cases, this feature can cause problems: the phone may freeze when switching between networks, drain the battery, or make calls over the internet when your plan doesn't allow it.
Many device owners Redmi And Poco Some users encounter situations where strange duplicates or notifications for Wi-Fi calls appear in their call logs, even though they intended to use regular voice calls. This happens because networks are prioritized automatically, and the smartphone persistently tries to use the wireless connection for voice calls. It's possible to eliminate these calls, but the approach will depend on the specific model and software version.
In this article, we'll cover all available methods for disabling this feature, from standard phone settings to hidden engineering menus. We'll also examine the reasons why the system might automatically activate this mode and how to prevent unnecessary charges or battery drain.
Why are Wi-Fi calls failing on Xiaomi smartphones?
Function VoWiFi (Voice over Wi-Fi) was introduced by telecom operators to improve coverage in buildings with thick walls or in remote areas. Smartphones XiaomiHaving received support for this technology, modems begin to aggressively search for available networks to transmit voice traffic. This behavior is built into the modem's operating algorithms, which consider an internet connection more stable than a weak cell tower signal.
The main cause of unwanted Wi-Fi calls is the network priority setting. If the phone menu is set to "Prefer Wi-Fi," even if there are 3-4 bars of cellular data available, the phone will ignore it and use the home router. This can lead to dropped calls if the internet connection is overloaded with torrents or video streaming.
⚠️ Attention: On some mobile plans, minutes spent using Wi-Fi Calling may be billed separately or not included in the main package. Check your plan terms with your operator before using this feature.
In addition, there are software glitches in the shell MIUIWhen the system settings are reset after a system update, the feature is forced to reactivate. The user may not notice the handset icon with the Wi-Fi symbol in the status bar until the bill arrives or sound quality issues begin.
Disabling the function through the standard settings menu
The easiest and safest way to disable Wi-Fi calls is to use the standard operating system interface. AndroidIn most cases, changing one setting is enough to stop your phone from using the internet for calls. The procedure may vary slightly depending on the firmware version.
First, you need to go to the SIM card settings section. Typically, the path looks like this: open Settings, then select the item SIM cards and mobile networksHere you'll see a list of installed SIM cards. Click on the one you're having problems with or want to reconfigure.
☑️ Disabling algorithm in settings
In the menu that opens, find the switch Wi-Fi calling (or Wi-Fi Calling). Toggle it to the off position. If there's no such switch, look for a "Use" or "Preferred Network" button. In this case, select "Mobile Network" or "Prefer Cellular Network."
It is important to note that on dual SIM phones Xiaomi Settings are applied individually for each SIM card. Disabling the feature on one SIM card doesn't mean it will be disabled on the other. Check both tabs to ensure the results are correct.
Settings inside the Phone app
In some versions of the shells from Xiaomi Call management has been moved directly into the Phone app. This is especially relevant for global firmware versions, which use the standard interface. Google Dialer, or for customized versions MIUI Dialer.
Open the phone app and tap the three dots in the upper right corner of the screen (or the "Settings" button in the lower right corner, depending on your version). Select "Settings" from the drop-down menu. Settings. Next, find the section Accounts or immediately Wi-Fi calling.
More detailed controls may be available here. For example, some models allow you to configure the feature's behavior: "Never use," "Use only when signal is weak," or "Always use." To completely disable Wi-Fi calling, select "Never."
| Setting option | Description of behavior | Recommendation |
|---|---|---|
| Included | The phone always prioritizes Wi-Fi for calls | Not recommended unless there are problems with cellular communication. |
| Only when the signal is weak | Automatic switching when GSM/LTE signal is lost | The optimal option for most users |
| Off | Only mobile operator networks are used | Choose for traffic savings and stability |
Internet call history is also often hidden in this section. If you want to not only disable this feature but also remove visual traces of its use, clear your call log by filtering by connection type, if this option is supported by your software version.
Hidden Google Dialer Settings
In the Google Phone app, you can enter #4636# into the dialer to access the test menu, which sometimes also displays the VoWiFi status, but changing the settings there requires caution.
Using the Engineering Menu for Advanced Users
If standard methods do not help or the menu item is missing (which happens on some models Redmi Note or Poco With stripped-down firmware, you can use the engineering menu. This is a powerful diagnostic tool that provides access to hidden modem parameters.
To enter the engineering menu, open the Phone app and dial the combination ##6484## (to enter the CIT menu) or ##4636## (for the testing menu). We're interested in the second option. In the list that opens, select Phone information (Phone Information).
Scroll down to the section Set Preferred Network TypeAlthough here they mainly change the network type (LTE/WCDMA), sometimes there is a checkbox next to it VoWiFi Provisioned or Enable VoWiFiUnchecking this option completely prevents the phone from registering with the Wi-Fi network for voice calls at the modem level.
⚠️ Attention: Be extremely careful when using the engineering menu. Changing network settings (for example, selecting 2G only) may result in a complete loss of connection. Remember the original settings before making any changes.
It is worth considering that on new versions Android (12, 13, 14) Access to these settings via codes may be blocked by the manufacturer for security reasons. In this case, this method will not work, and you will have to find alternatives.
Removing call shortcuts and widgets
Often, when users use “Wi-Fi calling,” they don’t mean the technology itself, but rather specific shortcuts or widgets on the desktop that lead to internet calls (for example, through operator services or pre-installed applications like Google Duo or Skype, if they are integrated into the system).
To remove visual noise, hold down the icon on your desktop. If the "Uninstall" menu or the trash bin appears, drag the shortcut there. This will only remove the app link, not the app itself. To completely uninstall, go to Settings → Apps → All apps, find the unnecessary service (for example, “Wi-Fi Calls” from the operator) and press Delete or Disable.
Also check the Tools or Services folder, which are often pre-installed on XiaomiThere may be a "Wi-Fi Calling" app from the manufacturer or a localized carrier app. It's safe to disable it if you don't plan to use it.
If it's the widget in the notification shade that constantly prompts you to connect to Wi-Fi for calls, you can remove it by editing the Quick Settings panel. Pull the notification shade down, tap the pencil (edit mode), and remove the icon. Wi-Fi Calling from the active panel.
Specifics of working with different telecom operators
Wi-Fi Calling functionality varies greatly depending on the SIM card you use. Major carriers (MTS, Beeline, Megafon, Tele2) implement this technology differently on their devices. Xiaomi.
- 📱 MTS: Often requires installation of the profile application "MTS Wi-Fi" for older models, but on new ones Xiaomi Works natively. Can be disabled in the SIM card settings.

If the function turns on again and again, the service may be activated on the operator side.
How to check the status on the operator's side?
Call customer support or enter the service check USSD command (usually *111# or similar for your region) to find out if the Wi-Fi Calling service is active on your number.
