Hello my name is Daniel.
If you're referring to a text message you had received and then deleted and now want to 'undelete', unfortunately that's not possible. Now there's technically a way to obtain the text message for legal purposes but that's going to involve a subpoena. Your carrier, Straight Talk, keeps your messages on file for about 6 months. With a subpoena they will be able to release the text to you if needed--otherwise that message is no longer the phone memory I'm afraid.
