Phone calls made over Wi-Fi are activated when the mobile operator signal is insufficient. This feature, available on Android and iPhone devices, allows voice calls and text messages to be sent over an internet connection.

How to activate Wi-Fi calling on Android and iOS?

This method is used especially in areas with weak cellular coverage or in places where the signal is difficult to reach, such as basements. However, since it is completely dependent on internet access, it does not work when there is no Wi-Fi network.

Phones primarily use the Wi-Fi connection when connecting to the internet. Wi-Fi is generally preferred because it is faster and has broader bandwidth than cellular connections. Despite this, traditional phone calls and SMS are still made over cellular networks by default.

Wi-Fi calls work with the hardware supported by the phone and the infrastructure provided by the operator. Most smartphones on the market today support this feature, and major operators also allow calls over Wi-Fi.

If the Wi-Fi connection is disabled, the device automatically switches to the mobile network. It is also possible to reach emergency services via Wi-Fi calls. However, location information is likely to be transmitted with less precision than cellular networks.

To enable the Wi-Fi calling feature on devices with the Android operating system, you need to enter the Settings menu and access the SIM card options from the Network and Internet tab. The feature is activated by activating the Wi-Fi Calling option from here.

The user may be asked to enter information for location sharing in emergency situations, such as an address. In addition to Google Pixel series devices, it is possible to specify whether the phone will use Wi-Fi calls as the default connection method. On Samsung Galaxy series devices, in addition to the Settings menu, Wi-Fi Calling can be opened directly from the three-dot menu in the Phone application or the Quick Settings panel.

The Wi-Fi calling feature is also available on iPhone devices. To enable this feature, you enter the Settings application and activate the Wi-Fi Calling option from the Cellular menu. At the same time, if the carrier supports it, an option is offered that allows Wi-Fi calls to be used on other devices connected to the Apple ID.

With the widespread use of Wi-Fi calling, communication is becoming more sustainable in areas with weak cellular signals. As smartphone hardware and operator infrastructures improve, Wi-Fi calling technology is becoming more accessible to a wider range of users.
