Stop my Edge 530 from prompting me about satellite messaging

Hello. My Edge 530 has recently been popping up a prompt during an activity asking me if I want to enable satellite messaging. There doesn't seem to be any way to answer this prompt, but it does go away with a button press. the prompt returns every few minutes. I don't want to enable satellite messaging and don't have any way of using this service anyway that I am aware of. Can anyone tell me how to stop my Edge from showing this prompt? Thanks.
