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 and receive phone calls over a WiFi network instead of a traditional cellular network. This feature is particularly useful in areas with poor or no cellular coverage, as it enables users to stay connected and make calls using their WiFi connection. WiFi calling works by routing voice calls over the internet, using the same technology as voice over internet protocol (VoIP) services. This means that as long as you have a stable WiFi connection, you can make and receive calls, send texts, and access other phone services.
To use WiFi calling, you need a compatible device and a SIM card from a carrier that supports this feature. Most modern smartphones support WiFi calling, and many carriers have started to offer this service to their customers. When you enable WiFi calling on your device, it will automatically switch to a WiFi network when available, allowing you to make and receive calls without using your cellular data. This can be especially useful for people who live or work in areas with poor cellular coverage, as it provides a reliable and cost-effective way to stay connected. Additionally, WiFi calling can also help reduce roaming charges when traveling abroad, as you can use local WiFi networks to make calls instead of relying on your cellular network.
