Is it possible to retrieve a deleted message from my phone?
What kind of message? Voice mail? Text? Email?
Voicemail: Probably not. Contact your carrier.
Text: If you backed up your phone to iTunes after you received the message but before you deleted it, you could restore your phone to the back up.
Email: Check the trash.
Best of luck.
it is a phone call i made
The answer is still the same. Read my post above.
