Users of modern smartphones often encounter the appearance of incomprehensible symbols at the top of the screen, and one of the most common of them is the icon telephone handset, located next to or over the wireless network icon. This visual marker appears suddenly and can be confusing, especially if you haven't manually changed your connection settings. In reality, it's not a system error or a sign of malware, but rather an indicator of a useful technology implemented by mobile operators.
The appearance of this symbol means that your gadget has entered the mode VoWiFi (Voice over Wi-Fi), which allows voice calls to be made over an internet connection rather than through standard cell phone towers. This is especially useful in areas with poor signal strength, where regular cellular service is intermittent or completely absent. In such cases, the smartphone automatically switches the voice call route to an available Wi-Fi network, ensuring high call quality and a stable connection.
Despite the obvious benefits, many subscribers want to know how to hide this icon or completely disable the feature if they don't need it. Below, we'll explain in detail how this technology works, its pros and cons, and provide step-by-step instructions for managing settings for various device models. Understanding the operating principles IP telephony will help you optimize traffic consumption and improve connection quality.
What's behind the icon: VoWiFi technology
The technology that is indicated by the handset icon on the Wi-Fi background is called VoWiFiIt represents an evolution of IP telephony standards, enabling the transmission of voice data as regular data packets over the Internet Protocol. For the user, this process is transparent: you dial a number as usual, but technically, the call is made not through the base station's radio channel, but through the router and the provider's broadband connection.
The main goal of implementation VoWiFi — a solution to the problem of "dead zones" in rooms with thick walls or in remote areas where the cellular signal is too weak. The smartphone automatically assesses the quality of the LTE/3G signal, and if it drops below a certain threshold and Wi-Fi is available, it automatically switches. An indicator lights up on the screen, informing you that an alternative communication channel is currently being used.
⚠️ Please note: Using VoWiFi may consume data traffic if you are not within range of your home or office network. Make sure your plan allows you to make these calls without incurring additional charges.
It's important to note that this feature requires support from your carrier and the availability of the relevant service in your plan. Most of the modern Big Four carriers have already enabled this option by default for their subscribers, but in some cases, activation is required via your personal account or a USSD request. Without carrier support, the icon simply won't appear, even if the phone is technically ready.
Advantages and disadvantages of Wi-Fi calling
Switching to an internet channel for voice communications has its own strengths and weaknesses, which should be considered before activating or disabling the feature. On the one hand, sound quality HD calls often outperform standard calls, especially in conditions with poor cellular reception. However, dependence on internet connection quality can lead to delays or disconnections if the channel is congested.
Let's consider the main pros and cons of this technology in more detail:
- 📶 Coating: The ability to make calls from basements, deep rooms, or country houses where only one network line can reach you.
- 💰 Roaming: In many cases, incoming calls via Wi-Fi while roaming are charged as regular local calls, allowing you to save on your calls abroad.
- 🔋 Power consumption: Searching for a Wi-Fi network and maintaining a connection can drain battery power faster than using standby mode on your cellular network.
- 🌐 Provider dependency: If your internet provider is experiencing problems or is performing maintenance, you may be without connection, even if the nearby cellular network is working perfectly.
Another important aspect is switching between networks. Modern smartphones can seamlessly transfer calls from Wi-Fi to cellular networks and back without interrupting the connection, but this feature isn't available on all devices. On older models or with a weak signal, the transition may be accompanied by a brief loss of audio or a complete disconnection.
How to disable the icon on Android (Samsung, Xiaomi)
Managing Wi-Fi calling on devices running the operating system Android The setting may vary depending on the manufacturer and shell version. In most cases, the setting is located in the telephony menu or general connection settings. If you want to remove the icon, you'll need to find the corresponding toggle and disable it.
For devices Samsung The setup path usually looks like this: open "Settings," go to "Connections," and find "Wi-Fi Calling." Within this menu, slide the switch to the "Off" position. On some models, the path may be slightly different: Settings → Phone → Wi-Fi Calling.
In smartphones Xiaomi (MIUI) and Poco The logic is similar, but the interface may have a different name. Often, the setting is hidden in the Phone app: tap the three dots in the corner of the screen, select "Settings," then "Calling Accounts," or directly select "Wi-Fi Calling." If this option is missing, your carrier may not support this feature or it's blocked by your firmware.
☑️ Check before disconnecting
It's worth remembering that after disabling this feature, the icon will disappear, and the phone will stop using Wi-Fi for voice calls, relying solely on the cellular network. If coverage is good in your area, this won't cause any problems. However, in "silent" areas, the phone will display "No Network," even though the Wi-Fi router may be working properly.
iPhone Setup: Where to Find the Switch
For smartphone owners Apple This feature is also available, and it's quite easy to manage in iOS. The handset icon against the Wi-Fi background on an iPhone means the same thing—the mode is activated. Wi-Fi CallingTo change settings, you don't need to search through complex engineering menus; everything is located in the standard settings app.
To control, go to the menu Settings → Phone → Wi-Fi CallingHere you'll see the "Wi-Fi Calling on This iPhone" toggle. If it's on (green), the feature is enabled, and an icon will appear in the status bar when connected. Turning this toggle off will remove the icon and prevent Wi-Fi calling from being used.
Interestingly, the Apple ecosystem includes the ability to broadcast calls to other devices. This menu may also include an option called "Add calls to other devices," which allows you to receive calls on your iPad or Mac if they're connected to the same Wi-Fi network. Disabling the primary feature also disables this feature.
| operating system | Path to setup | Function name | Default Status |
|---|---|---|---|
| Android (Samsung) | Settings / Connections | Calling over Wi-Fi | Enabled (often) |
| Android (Xiaomi) | Phone / Settings | Use Wi-Fi | Off |
| iOS (iPhone) | Settings / Phone | Wi-Fi calling | Depends on the operator |
| Android (Stock) | Network and Internet / Mobile Network | Wi-Fi Preference | Off |
⚠️ Note: The settings interface may change after updating your operating system. If you don't find the item in the specified location, search for "Wi-Fi" in the settings.
Impact on pricing and roaming
One of the most important questions users have is how much it costs. Technically, a Wi-Fi call is charged by your carrier like a regular outgoing call, according to your plan. If you have unlimited minutes to numbers in your region, they will also be free over Wi-Fi. However, there are some nuances associated with calling abroad.
When in international roaming, use Wi-Fi Calling This can be a lifesaver. Many carriers allow incoming calls over Wi-Fi to be charged as domestic calls, meaning they're free, even if you're in another country. The rules for outgoing calls may vary: sometimes they're charged as calls from your home network, while other times, roaming rates for the country you're visiting apply.
It's important to distinguish between Wi-Fi calls and calls made via messaging apps (Viber, WhatsApp, Telegram). With messaging apps, you use your data plan, and the other person needs to be online. With VoWiFi, you call a regular phone number, and the other person is charged the same minutes as for a regular call.
What happens if the internet connection runs out during a call?
If you're using VoWiFi and your internet connection is interrupted, a modern smartphone will attempt to switch the call to a cellular network (LTE/3G). If there's no cellular coverage at that location, the call will be disconnected.
Why doesn't the icon disappear after disabling?
Sometimes users encounter a situation where they seem to have disabled the feature in the settings, but the Wi-Fi handset icon remains lit. This can be caused by several reasons. The first and most common is interface caching. The operating system doesn't always update the status bar immediately, and the icon may become stuck.
The second reason is the priority of operator settings. Some mobile operators force this service to be activated at the network level, and the phone settings may not have full effect. In this case, even if you've turned off the toggle switch, the network may initiate a connection through its profile.
The third reason is a software glitch. A glitch in the system process responsible for telephone communications (Phone Services) may cause icons to display incorrectly. In this case, a simple device reboot or network settings reset will help.
Troubleshooting connection and display issues
If the icon is lit but calls aren't connecting, or if you want to use it but it doesn't appear, it's worth running a basic diagnostic and making sure the service is activated with your carrier. This can be done through your personal account or by calling customer support. Without activation on the SIM card, phone settings are useless.
Secondly, check for software updates. Manufacturers often release patches that improve compatibility with carrier networks. Go to Settings → About phone → System update and check for new software versions.
If all else fails, you can try resetting your network settings. This will delete saved Wi-Fi passwords and Bluetooth settings, but will return your network settings to factory defaults, which often resolves the issue of stuck icons.
Is it safe to bank using Wi-Fi Calling?
Yes, VoWiFi technology uses the same encryption protocols as regular cellular calls (or even more modern ones). Voice traffic is encrypted between your phone and the carrier's gateway, making it more difficult to intercept than open Wi-Fi networks in cafes. However, the Wi-Fi channel itself must be password-protected.
Can I use VoWiFi if my SIM card is blocked?
No. VoWiFi technology requires an active SIM card registered with the operator. Without a SIM card or if the number is blocked, the service will not work, as authentication occurs through the cellular network, even if the voice connection is over the internet.
Does the Wi-Fi handset icon affect internet speed?
The icon itself is simply an indicator. However, making a voice call over Wi-Fi generates a constant data stream, which can slightly reduce the available bandwidth for other tasks, such as downloading files or watching 4K video, especially at low speeds.
