WiFi calling enables users to make and receive phone calls over a WiFi network rather than relying on a cellular network. This is useful when a stable WiFi connection is present.

The technical requirements of WiFi calling

Network Requirement

To use WiFi calling, users need a compatible smartphone and a WiFi network. The feature is typically supported on modern smartphones, and most carriers offer WiFi calling as part of their services. Third Party Applications such as WhatsApp offer WiFi Calling.

Improved Coverage

Wi-Fi calling can help users make calls in areas with poor cellular reception, such as indoors or in rural locations. As long as there’s a WiFi connection, users can place calls without relying solely on cellular towers.

Seamless Transition

WiFi calling enables a seamless transition between WiFi and cellular networks during an ongoing call. For example, if a user starts a call on WiFi and then moves out of WiFi range, the call can automatically switch to the cellular network without dropping.

International Calls

WiFi calling can be really beneficial when making international calls. Users can make calls to other countries using WiFi, potentially avoiding international calling charges.

Text Messaging

In addition to voice calls, WiFi calling often supports text messaging (SMS) and multimedia messaging (MMS).

Emergency Calls

Emergency calls are typically routed through cellular networks even when connected to WiFi. This ensures that emergency services can locate the caller using the cellular connection.

It’s important to note that the availability of WiFi calling depends on the carrier and the specific smartphone model. Users need to enable WiFi calling in their phone settings, and carriers may provide specific guidelines on using this feature. Additionally, carriers may offer WiFi calling as part of their service plans, and some may charge for international calls made through WiFi calling.
