Probably depends on the radio station and area but I work in one and we're actually using something much higher quality for remote radio, for example: https://www.prodys.net/portable-codecs-audio/quantum-lite-2/

If course it has to be pre-planned, someone needs to have the hardware with them. So sometimes there's a spontaneous connection over normal mobile phone. That's something that everyone has with them at all times.
