How do I retrieve an accidentally deleted on a Samsung Galaxy S5

[Janis_1]

I accidentally deleted the voice mail before I even listened to it. Please help!

Voice mail is not stored on the phone. That is kept by your service provider. Many have the option to undelete a message you have deleted when you call the voice mail. I would check that first. If that doesn't work, check with your carrier. They would be the only ones who could retrieve it.
