Delete entire SMS history from iPhone 5?

I noticed that my deleted SMS on iphone 5 is still stored in the phone. How do I Bauer that deleted messages are completely deleted?

Boil the phone

You can't. It is impossible to delete that data permanently, even if you restore your phone it is still recoverable for a long time. Deleting the messages from the messages list in the app is good enough to keep any regular person from seeing the messages. They are also stored in your wireless carrier's history, so even deleting them from the phone does not make them unviewable by anyone else.

  • My iPhone has been charging an entire night but won't turn on? It has water damage but was repaired with minor issues as expected.
