Text messages can be retrieved after being deleted. While you cannot recover deleted text messages on your phone, you — or someone else — can purchase software programs that allow your computer to uncover and read your deleted text messages.
When you delete text messages on your cellphone, you are actually telling your phone not to show you these messages any longer. However, your cellphone still stores the data on your phone. Therefore, when you purchase and download a text-recovery software program, the program extracts the data from your cellphone or smartphone and produces the lost text messages to you verbatim.
