Just as Apple made listening to your voicemail better with the iPhone's Visual Voicemail, so, too, is undeleting email on the iPhone better than on earlier cellphones. Thanks to the way the phone works, you have a longer window in which to undelete an email before it's permanently lost.
The iPhone will periodically clear deleted voicemails (deleted voicemails are usually removed when you sync your iPhone with your computer), but if you accidentally deleted a voicemail, want it back, and haven't synced your phone recently, here’s how to get that message back:
- Tap the Phone app.
- Tap the Voicemail icon in the bottom right.
- In the voicemail list, if you have deleted messages that have'’t been cleared, you'll see an item at the bottom called Deleted Messages. Tap it.
- Here you'll see all the voicemails you've deleted that are still on your phone. Tap the voicemail you want to undelete. In iOS 7, this will reveal some options beneath the voicemail. In iOS 6 or earlier the selected voicemail will be highlighted.
- In iOS 7, tap Undelete beneath the selected voicemail. In iOS 6 or earlier tap Undelete at the bottom left.
- Tap the Voicemail arrow icon at the top left to be returned to the main Visual Voicemail window and the voicemail you just undeleted will be present--safe, sound, and ready for listening.
- If a voicemail doesn't appear in the Deleted section, it may be gone for good. There are some programs that will let you browse your iPhone's file structure, though, and you may be able to find some voicemails that way.
