Used to be Everton app but stuff getting a membership just for that. I usually just type into google Everton v (Opponent) radio and there has been a few to listen to. Was via talksport last time I think.
You need a paid membership to listen to the Everton radio now. I always used to listen to it in the car on the way to work but can't this season. I just googled live radio for the last game and listened to it on talksport.
