Is there any way possible that you can find lost text messages...and bring them back up on your computer to print out?? from a cell phone number you have???
if you already deleted it on your phone, i don't think you would still be able to recover it unless you have a backup and synchronize it with your computer.
They can be retrieved from your provider's or the sender's servers, but no company will do that without a subpoena, and generally only in criminal investigations. This involves going through backup tapes and is a very involved process.
