What is WiFi calling and how does it work?
WiFi calling, also known as Voice over WiFi (VoWiFi), is a technology that allows users to make phone calls using a WiFi network instead of a cellular network. It works by using the internet to transmit voice data, allowing users to make calls even in areas with little to no cellular coverage. This technology is especially useful in areas with poor cell reception, such as rural areas or indoor locations with thick walls.
WiFi calling uses a combination of the device’s WiFi capabilities and a VoIP (Voice over Internet Protocol) system to connect calls. When a user makes a call, their device connects to a nearby WiFi network and sends the voice data to the recipient’s device over the internet. This allows for clearer and more reliable calls, especially in areas with poor cellular coverage.
Why is my WiFi calling not working?
There could be several reasons why your WiFi calling is not working. One common reason is that your WiFi network may not be strong enough to support VoWiFi calls. Weak WiFi signals can cause dropped calls, poor call quality, and other issues. Another reason could be that your device or SIM card is not compatible with WiFi calling. Additionally, some carriers may not support WiFi calling on certain plans or in certain areas.
To troubleshoot the issue, try checking your WiFi network strength, ensuring that you have a strong and stable connection. You can also check with your carrier to see if WiFi calling is supported on your plan and in your area. Finally, make sure that your device is compatible with WiFi calling and that you have the necessary settings enabled.
How do I enable WiFi calling on my device?
To enable WiFi calling on your device, you’ll need to check your device’s settings. The exact steps may vary depending on your device and operating system, but generally, you’ll need to go to your device’s settings, then select “Connections” or “Wireless & networks,” and finally toggle on “WiFi calling” or “VoWiFi.” You may also need to enable “Advanced Calling” or “VoLTE” (Voice over LTE) to activate WiFi calling.
Once you’ve enabled WiFi calling, you may need to restart your device to complete the setup process. You can then check your device’s status bar to see if WiFi calling is active. Some devices may display a “WiFi” or “VoWiFi” icon, while others may show a “VoLTE” indicator. If you’re still having trouble, you may want to consult your device’s user manual or contact your carrier for assistance.
