Wi-Fi calling, also known as VoWiFi (Voice over Wi-Fi), is a technology that allows mobile phone voice calls and text messages to be made over a Wi-Fi network instead of using traditional cellular towers
. This means that when cellular coverage is weak or unavailable, but a Wi-Fi connection is accessible, calls and texts can still be sent and received seamlessly.
How Wi-Fi Calling Works
- Wi-Fi calling uses Voice over Internet Protocol (VoIP) technology to route calls over the internet to your mobile carrier's network, which then connects the call as if it were made via a cellular tower
- Compatible smartphones automatically switch between cellular and Wi-Fi networks to maintain call quality without interrupting the call
- The calls use your regular phone number and dialer app, providing the same user experience as a normal cellular call
Benefits of Wi-Fi Calling
- Improved call quality and reliability in areas with poor cellular reception, such as indoors or remote locations
- No additional hardware or apps are required; it works with your existing phone number and carrier service
- Can reduce roaming charges when traveling internationally by using Wi-Fi networks instead of cellular roaming
- Extends battery life by avoiding weak cellular signal searching
Differences from Other VoIP Apps
Unlike apps like WhatsApp or FaceTime that also use internet for calls but require both parties to have the app, Wi-Fi calling works through your carrier and phone number, allowing calls to any regular phone number without special apps
. In summary, Wi-Fi calling enables making and receiving standard phone calls and texts over Wi-Fi networks, improving connectivity where cellular signals are weak or unavailable, while using your existing phone number and carrier service seamlessly
