How to permanently delete text messages from iphone

To securely and permanently delete text messages from iPhone, simply deleting them or performing a factory reset may not be sufficient, as data recovery tools can sometimes retrieve deleted information. Here are some effective methods to ensure your messages are permanently erased:

1. Overwrite Data with a Secure Erasure Tool:
   Use specialized iPhone data erasure software that performs multiple overwriting passes on your device's storage. 
   These tools overwrite the storage sectors multiple times, making data recovery virtually impossible.
2. Reset Your iPhone to Factory Settings:
   Perform a factory reset via Settings > General > Reset > Erase All Content and Settings.
   To increase security, after resetting, you can restore your iPhone from a clean backup or set it up as new.
   Note: Factory reset alone may not securely overwrite data; combine this with a secure erasure tool.
3. Use a Secure Data Wipe Before Selling:
   After factory resetting, consider connecting your iPhone to a computer and using third-party software to securely delete text messages from iPhone.
   Some tools allow you to perform multiple overwriting passes, ensuring data is unrecoverable.
4. Physical Destruction:
   For highly confidential information, physically destroying the device's storage (e.g., SSD or flash memory chip) guarantees data destruction but makes the device unusable.
