How do I retrieve a deleted voicemail from a Samsung Note 5?

[AC Question]

I mistakenly deleted an important voicemail and would like to restore it.

Hi, I don't think you can - you could try contacting your service provider - they might be able to assist?

Welcome to Android Central! I agree with the tall guy. Voicemails aren't saved to your phone--they're saved on your carrier's servers.
