VoLTE (Voice over LTE) is the technology that enables you to make mobile phone calls over the 4G (LTE) network. With VoLTE technology, you can make mobile calls faster with high-quality audio, while also being able to browse the Internet at 4G speeds during a call.

The Giga WiFi Calling service, which incorporates VoLTE technology, is gradually being activated automatically and free of charge for Vodafone subscribers who have a 4G device with VoLTE capability.

All you need to do is set up the WiFi Calling service on your 4G VoLTE device.
