What is Wifi Calling?

Wi-Fi Calling is a feature that lets you make and receive phone calls, text messages, and even video calls over a Wi-Fi network instead of using your mobile carrier’s cellular network. When your phone is connected to a Wi-Fi network, it routes your calls and texts through the internet rather than relying on a cell tower.

Wi-Fi Calling is a technology that allows you to make and receive voice calls, send text messages (SMS), and sometimes even place video calls using a Wi-Fi internet connection instead of your mobile carrier’s traditional cellular network. This feature is especially useful in areas with poor or no cellular signal but reliable Wi-Fi access — such as inside buildings, basements, or remote locations.

Here’s how it works:

• When enabled, your smartphone automatically switches to Wi-Fi for calls and texts when connected to a Wi-Fi network and cellular signal is weak or unavailable.
• The call or message is transmitted over the internet using Voice over IP (VoIP) technology, then routed through your carrier’s network so it functions just like a regular call or text.
• Your phone number remains the same, and recipients don’t need to do anything special to receive your Wi-Fi calls.

Benefits of Wi-Fi Calling:

• Improved call quality and reliability in areas with weak cellular coverage.
• Seamless integration with your existing phone number and contacts.
• No extra charges — calls and texts typically count toward your existing plan.
• Works internationally in some cases, allowing you to make calls back home without roaming fees (depending on carrier policies).

Requirements:

• A compatible smartphone (most modern smartphones support Wi-Fi Calling).
• Wi-Fi Calling enabled in your phone settings.
• A stable Wi-Fi connection.
• Carrier support (most major carriers now offer this feature).

To use Wi-Fi Calling, you usually need to activate it manually in your phone’s settings under the "Phone" or "Connections" menu. Once set up, it works seamlessly in the background whenever needed.
