How to Retrieve Deleted Voicemail Messages
So, you deleted a voicemail message and now you wish you had saved it. Is it gone for good? You might be able to retrieve your deleted voicemail messages; it depends on the situation and your wireless provider.
If you're a use of TMobile, Metro PCS or Boost Mobile, you should call your wireless provider to find out if the messages are lost forever. AT&T, Verizon and Sprint will help you to retrieve deleted voicemail messages.
AT&T and Verizon Customers
If you accidentally pressed "7" (to delete a voicemail message) instead of "9" (to save a voicemail message), you should listen for the prompt to say "Check erased messages." Press the "1" button on your keypad, followed by the "9" button. Listen to the deleted voicemail message, then press "9" to confirm you want to save it.
Sprint Customers
If you accidentally pressed "7" (to delete a voicemail message) instead of "3" (to save a voicemail message), stay on the line; do not hang up. When the automated voice prompt instructs you to "Press star (*) three to check erased messages," press the star (*) key, followed by the "3" key. Listen to the deleted voicemail message, then press "3" to save the message.
Things to Consider
If you deleted a voicemail message at an earlier date, you should call your service provider for details on retrieving a deleted voicemail message. If your service provider cannot offer assistance, consider using recovery software to retrieve deleted voicemail messages.
