The appearance of an unusual icon in a smartphone's status bar often causes confusion, especially if the user is unfamiliar with modern voice communication technologies. A symbol depicting a telephone handset combined with a Wi-Fi logo indicates the function is activated. VoWiFi (Voice over Wi-Fi). This technology allows you to make and receive calls over a wireless network, bypassing standard cell phone towers. In most cases, this is a useful option, improving connection quality in buildings with thick walls or in areas with poor coverage.
However, there are situations when the user needs to forcibly disable this mode. For example, if the data plan doesn't include free internet calls, or if the smartphone constantly tries to switch to a weak Wi-Fi connection, interrupting calls. The icon can also be visually distracting or indicate that the device is ignoring the SIM card in favor of the router, which isn't always desirable. In this article, we'll cover how to manage this feature on different devices.
It's worth noting that the deactivation process may differ depending on your gadget model and operating system version. Interfaces Android And iOS have their own menu features, and some smartphone manufacturers, such as Samsung, Xiaomi or Huawei, may hide the necessary switches in deep submenus. We'll look at universal solutions that will help you restore the familiar appearance of the status bar.
What does the Wi-Fi handset icon mean?
An icon that combines a phone and a wireless network symbol lets you know that your smartphone The device has switched to Voice over IP mode. This isn't just an indicator of a connection to the router, as with regular internet. It's a signal that voice traffic is now being routed through the internet, ensuring high-quality audio (HD Voice) and a stable connection in areas where regular cellular coverage is poor.
Technology VoWiFi is becoming the de facto standard for modern telecom operators. It allows for uninterrupted connection in basements, offices with double-glazed windows, or remote country houses. For the user, this means they can talk even if the screen displays "No Service," as long as Wi-Fi is working. However, this feature requires operator support and proper device configuration.
⚠️ Attention: Using VoWiFi can consume your home or mobile data plan. While many carriers don't charge separately for Wi-Fi call minutes, the data usage itself should be included if you have a limited data plan.
It's important to distinguish this icon from the standard Wi-Fi indicator. The standard icon indicates internet access, while the handset with waves indicates active phone service. If you see this symbol, the incoming call will be made via the internet, and the minutes will be counted according to your VoIP plan.
Reasons for its appearance and why it should be disabled
There are several scenarios in which activation Wi-Fi Calling This happens automatically or is required manually. Understanding the reasons will help you decide whether to disable the feature. Users often don't even notice when the mode is enabled, as modern firmware strives to ensure the best possible connection quality by any means possible.
- 📶 Weak cell phone signal: The phone automatically switches to Wi-Fi to avoid interrupting the connection if the GSM/LTE signal level drops below a critical threshold.
- 🏢 Buildings with screening: In offices, shopping centers, or subways, where conventional frequencies don't penetrate concrete, smartphones are forced to use the internet channel for voice communications.
- 🌍 Roaming: When abroad, connecting via Wi-Fi allows you to avoid international mobile phone charges by using your home number.
- 🔋 Power consumption: Searching for a cellular network in a poor reception area quickly drains battery life, while stable Wi-Fi can be more energy-efficient for voice calls.
Despite the obvious advantages, there are cases when the function is necessary deactivateFor example, if your router is overloaded with devices, the audio quality may become robotic or intermittent. Furthermore, some older router models cannot properly prioritize voice traffic, causing calls to drop out or be delayed.
Another reason is privacy and routing. When calling over Wi-Fi, your IP address and location (via access point) may be visible to the carrier differently than during a standard call. For some corporate users or security professionals, this may be an undesirable vector for location data leakage.
How to disable the icon on Android (Samsung, Xiaomi)
In the operating system Android The path to settings may vary, but the logic remains similar. Manufacturers often change the layout of menu items, so it's important to search for keywords related to networking and calls. On devices Samsung And Xiaomi These functions are usually placed in separate subsections for the convenience of the user.
For owners Samsung The usual procedure is as follows: open Settings and find the "Connections" or "Network & Internet" section. Inside, look for "Wi-Fi Calling." If the switch is active, toggle it to the "Off" position. Afterward, the icon should disappear from the top status bar within a few seconds.
On smartphones Xiaomi (MIUI) The situation can be more complicated. The setting is often hidden in the SIM card menu. You need to go to "Settings," select "SIM cards and mobile networks," then tap the specific SIM card. There may be an option called "Wi-Fi calling." If it's not clearly visible, try searching for "Wi-Fi calling" in the settings search.
☑️ Disabling checklist on Android
In some cases, especially on custom firmware or carrier-provided phones, there may be no standard switch. In these cases, you can try entering a special USSD code in the dialer, which will grant access to a hidden testing menu. However, be careful: changing parameters in the engineering menu may affect the operation of the communication module.
##4636##
##4636##After entering the code, the testing menu will open. Select "Phone Information." Scroll down and find the "VoWiFi Provisioned" or "Wi-Fi Calling" toggle. Disabling this option will forcibly remove the icon and prevent your phone from using the internet for calls.
Removing the icon on iPhone (iOS)
Users iPhone You may also encounter the operator display with the addition "Wi-Fi". In the ecosystem Apple The control of this function is implemented more centrally and usually does not require deep diving into technical menus. Interface iOS It is characterized by stability, so the instructions are suitable for most current versions of the system.
To disable the feature, go to Settings, then select the item Cellular communications (or "Mobile data"). Next, you need to find the section Wi-Fi callingThere will be a toggle switch inside that needs to be set to the off position. The system may ask for confirmation, warning you of possible changes to pricing.
If you have dual SIM iPhoneMake sure you've disabled the feature for the SIM card you're using, as the settings may be specific to each number. Once disabled, the "Wi-Fi" icon next to the carrier's name in the upper left corner should disappear, and your phone will revert to using the standard cellular network for voice calls.
| Parameter | Standard mode | VoWiFi mode |
|---|---|---|
| Communication channel | Cellular operator towers (GSM/3G/4G) | Internet (Wi-Fi router) |
| Addiction | Terrain coverage | Wi-Fi speed and stability |
| Indicator | Signal sticks | Tube + Wi-Fi |
| Sound quality | Depends on the tower load | Usually higher (HD Voice) |
In this case, you may need to update your operator profile or reset your network settings if the standard method does not work.
Hidden settings and engineering menu
If standard methods do not help to remove the obtrusive icon, you can resort to more advanced methods through engineering menuThis tool is intended for developers and testers, but it allows access to hidden radio module parameters. Be careful: incorrectly changing the settings in this section may result in loss of connection.
Many Android smartphones use a code to access advanced settings. ##4636##In the menu that opens, select "About phone." Here you'll find the option "Set preferred network type." Changing this setting can force the phone to ignore VoWiFi, although this isn't the default method for disabling it.
Risks of using the engineering menu
Changing settings in the engineering menu may result in incorrect modem operation, loss of IMEI, or failure to register on the network. Use only if you are confident in your actions and know which setting you are changing.
There's also a method via ADB (Android Debug Bridge) for advanced users connected to a PC. Using the command line, you can send a system command to disable a service. For example, the command might look like changing a global variable in the Android settings database. However, the command syntax varies greatly depending on the OS version and manufacturer.
On devices with permissions Root You can use special manager apps that allow you to edit system configuration files (build.prop or XML files in the carrier folder) to disable VoWiFi support at the firmware level. This is a radical method that guarantees the icon will disappear, but will permanently disable the feature until you reflash the firmware.
⚠️ Attention: Settings interfaces and access codes may change with firmware updates. If the code doesn't work or the menu appears different, please refer to the official documentation from your smartphone manufacturer or the support forum for your specific model.
Problems after disconnection and their solutions
After you've removed the phone's Wi-Fi icon, you may experience reduced connection quality. This is normal, as you've forced your device to a less stable channel (cellular network). If you're in a "no-call" zone inside a building, your phone may lose signal altogether or display "No Network" even though Wi-Fi is working.
In some cases, the icon may return on its own. This happens if your carrier forcibly activates the service or if "Prefer Wi-Fi" is checked in the settings. Check your settings again, especially after a system update or device reboot. A complete reset of network settings can sometimes help.
- 🔄 Reboot: After changing the settings, be sure to restart your smartphone for the changes to apply to the communication module.
- 📡 Airplane mode: Toggle Airplane Mode on and off to force a re-registration of your device to the network.
- 🗑️ Network reset: If the problem persists, perform a network settings reset (not data reset!), this will return all network settings to factory defaults.
If the icon is gone, but you're also receiving incoming calls, check if your phone is in "Do Not Disturb" mode or call forwarding. Disabling VoWiFi shouldn't affect your regular cellular service, but in rare cases, a software glitch can disrupt the SIM card. In this case, remove and reinsert the SIM card.
Frequently Asked Questions (FAQ)
Does the Wi-Fi handset icon affect internet speed?
The icon itself doesn't affect speed. However, an active voice call over Wi-Fi can consume some bandwidth. If you have a low internet connection, YouTube videos may start buffering during the call. Modern routers can prioritize voice traffic, minimizing this effect.
Do operators charge for Wi-Fi calls?
In most cases, you'll be charged the same as a standard minute of call according to your plan. However, if you're abroad, Wi-Fi calls to numbers in your home country are often charged as regular calls, not roaming charges. Check with your carrier, as these may vary.
Why did the icon appear without my participation?
Carriers are increasingly implementing this feature by default. When updating your carrier profile or resetting your phone, the "Wi-Fi Calling" setting may automatically activate if your SIM card and phone support it.
Is it possible to call emergency services (112) via Wi-Fi?
While this is technically possible, it's not recommended to rely on it in emergency situations. Wi-Fi location detection is less accurate than using cell towers, which can hinder rescue efforts. It's best to use the regular cellular network for emergency calls.
