Everyone wants to delete the text messages we get on our iPhones sometimes. Whether that's because you want to keep your Messages app tidy or because you want to keep a message private, a simple swipe usually takes care of things.

Or does it? It turns out that deleting text messages from your iPhone isn't so simple.

Try this: delete an SMS message from your iPhone, then go to Spotlight and search for the text of the message you just deleted.

In many cases, something disturbing happens: the text message appears in the search results. This also happens in some cases when you search within the Messages app.

Those text messages you thought were gone when you deleted them are still hanging around your iPhone, waiting to be found by someone who's determined and knows how to find them.

Why Text Messages Aren't Truly Deleted

Text messages hang around after you "delete" them because of how the iPhone deletes data. When you "delete" some kinds of items from the iPhone, they don't actually get removed. Instead, they're marked for deletion by the operating system and hidden so that they appear to be gone. But they're still on the phone. These files, like text messages, aren't truly deleted until you sync your iPhone with iTunes.

How to Permanently Delete iPhone Text Messages

If you want to truly and permanently delete text messages from your iPhone, there are a few steps you can follow.

1. Sync Regularly—Syncing with iTunes or iCloud is what actually erases items you've marked for deletion. So, sync regularly. If you delete a text and then sync your iPhone, the message really will be gone for good.

2. Remove Messages App from Spotlight Search—Your deleted messages can't appear in a Spotlight search if Spotlight isn't looking for them.

You can control what apps Spotlight searches and which it ignores. To do this:

  1. From your home screen, tap Settings
  2. Tap General
  3. Tap Spotlight Search
  4. Find Messages and move the slider to off/white.

Now, when you run a Spotlight search on your phone, text messages won't be included in the results.

3. Erase All Data or Restore to Factory Settings—These are pretty extreme steps, so I don't recommend using them as your first choice, but they do solve the problem. Erasing all data on your iPhone does just what it sounds like: it erases everything stored in your iPhone's memory, including your text messages marked for deletion. Of course, it deletes your music, email, apps, and everything else, too, but it solves the problem.

The same is true of restoring the iPhone to factory settings. This returns the iPhone to the state it arrived in when it came from the factory. Again, it deletes everything, but your deleted text messages will definitely be gone.

4. Use a Passcode—One way to prevent nosy people from reading your deleted text messages is to keep them from accessing your iPhone in the first place.

A good way to do that is to put a passcode on your iPhone that they have to enter before unlocking it. The standard iPhone passcode is 4 digits, but for extra-strength protection, try the more secure passcode you get by turning the Simple Passcode option off. Thanks to the Touch ID fingerprint scanner on the iPhone 5S and up, you can have even more powerful security.

5. Apps—Your deleted text messages can't be found if they're not saved at all. If you want to make sure not to leave a record, use messaging apps that automatically delete your messages after a set period of time.

Snapchat works this way, but it's not the only option. Here are a few similar apps available in the App Store:

Why Texts Are Never Truly Gone

Even if you remove a text message from your phone, it may not be truly gone. That's because it could be stored on your phone company's servers. Normal text messages go from your phone to your phone company, to the recipient. The phone company retains a copy of messages. These can be subpoenaed by law enforcement in criminal cases, for instance.

If you use Apple's iMessage, though, messages are encrypted from end to end and cannot be decrypted, even by law enforcement.
