Voicemail showing up on a different phone

Hi mmmm24,

If we understand correctly, you're seeing voicemail from someone else's device appearing on yours. Voicemail is a service offered by your wireless carrier, so for assistance with this, you'll need to reach out to them to ensure everything is provisioned properly for your account and SIM card.

Kind regards.

Stop sharing an Apple ID. You each need your own.

confidently incorrect, I’m having the same issue with a member of my family and we are on two separate carriers.

This is now expected behavior if you're sharing an Apple ID.
