VoLTE (Voice over LTE) is an advanced technology that delivers high-quality life-like sound across the 4G network. With Proximus VoLTE you experience ultra-clear voice quality and reduced background noise everywhere in Belgium. Conversations will sound more natural, almost as if the person at the other end of the phone call is right next to you.
Moreover, when combining VoWiFi with VoLTE, your phone will automatically switch over from a Wi-Fi signal to a mobile signal (4G), so your call won’t cut off if you lose your Wi-Fi signal. This is not possible when you’re calling over Wi-Fi with a separate app such as Skype, WhatsApp, etc. Calling or sending text messages is currently not yet available via 5G.
When calling over LTE, you don't use any data, just call minutes.
