felix doesn’t support WiFi calling or VoLTE at this stage, but VoLTE is a feature coming up in the not too distance future! While we don’t have it, this just means that when you’re on a call, your phone will switch to a 3G connection, so using data may be a little slower while you’re on a phone call.

If you need to use data while making a call, we suggest calling from apps such as Facetime Audio on iPhone, WhatsApp, or similar apps, or when connected to available WiFi.
