Method 1: Erase data from iPhone with Safewiper iOS Data Eraser
Maybe it is because you want to give away your old iPhone for a new one, or you don't want to expose these messages to your husband or wife, or you just need to clear up the phone memory since mobile phone always has a limited amount of storage space. Then, do you know any effective way to get the iPhone text messages deleted? Apple's application only provides you with the power to delete one contact at a time. And the deleted contacts can be recovered back easily with additional data recovery software.
