As a priority, calls are made via VoLTE if there is 4G coverage, otherwise via 2G (as today). If there is no mobile signal, and at the same time your device has access to a WiFi network, then calls are made via VoWiFi. On Samsung devices, VoWiFi can be preset to prioritize WiFi even when there is a mobile signal (recommended only in cases where the WiFi connection is good and at the same time the mobile signal is low). On Apple devices, after the software upgrade, from the settings – phone menu, the Wi-Fi calling option must be activated (or Wi-Fi Calling in the English menu).
