Voice over NR

High-speed wireless communication functionality

VoNR or 'Voice over New Radio' (also referred to as Voice over 5G or Vo5G) is a 5G high-speed wireless communication standard for mobile phones and data terminals, including Internet of things (IoT) devices and wearables.^[1] VoNR fully utilizes the 5G Standalone (SA) core and can have better voice quality than its predecessor Voice over Long Term Evolution (VoLTE).^[2] Call setup time is faster than VoLTE due to the inherent lower latency of 5G NR. 5G VoNR removes the LTE anchor allowing the voice call to stay on a 5G network.

VoNR calls are usually charged at the same rate as other calls.

To be able to make a VoNR call, the device, its firmware, and the mobile telephone provider must all support the service in the area, and be able to work together.
