VoiceMail is also known as voice mail, voice-mail, voice message or voice bank. When you lost an important voicemail or delete voicemails by accident, how to retrieve them in a simple way?
Note: Vociemail messages are held by phone computers and saved on their servers. The messages expire after a certain time and will be deleted from the company's servers. In this case, your lost Voicemail could not be recovered. In another case, you can restore them. If you have paid for visual Voicemail and download them from the server to your iPhone, when you deleted them from your iPhone accidentally, you have a chance to get them back.
Download and install on your computer that you used to back up your old iPhone. Run it and the interface below will pop up.
The tool can recover other data like videos from Camera Roll, pictures, contacts, SMS, etc. If you just need to restore Voicemail, you can click Voicemail on the left side of the window below. Then choose the items you want (Voicemail messages are not able to preview, you should select them all to recover), and save them to your computer.
Note: For the lost Voicemail message can be overwritten by new data, so please do not use your iPhone for anything after you lost the Voicemail message. If it's overwritten, you can never get it back.
