Wi-Fi Calling

Wi-Fi calling is a feature that allows iPhones and Android smartphones to make phone calls using a wireless Internet connection. It uses technologies called SIP (Session Initiation Protocol) and IMS (IP multimedia subsystem) to tunnel voice calls over the Internet. Instead of connecting to a cell tower, your smartphone connects to Wi-Fi, so there are no additional costs charged to your voice or data plan.

Wi-Fi calling can enhance call quality in areas with poor cell signal reception, and enable calling when no other signal is available.
