You can delete all your text messages in two ways: wipe them from the Messages app one conversation at a time, or erase your entire iPhone and restore from backup

The fastest method depends on whether you want to keep everything else on your phone. If you only want to clear messages, you'll use the Messages app and delete conversations in bulk. If you're willing to erase your whole device—say, before selling it or giving it away—you can factory reset the iPhone, which removes all messages along with everything else.

Neither method is when ready. Deleting conversations one by one takes a few minutes if you have dozens of threads. A full factory reset can take 30 minutes to an hour, depending on your phone's storage and internet speed. Both are permanent: once deleted, messages cannot be recovered unless you have a backup stored in iCloud or on a computer.

Key Takeaways

  • To delete messages without erasing other data, open Messages, tap Edit in the top left, select all conversations, and tap Delete.
  • Deleting a conversation removes all messages in that thread but leaves your photos, apps, and settings untouched.
  • A factory reset erases messages along with everything else on the phone, and takes 30 minutes to an hour to complete.
  • If you have an iCloud backup, you can restore your phone after a factory reset and get back your photos and apps, but not your messages if you deleted them before backing up.
  • Messages deleted from your iPhone may still exist on your carrier's servers for a limited time, but you cannot retrieve them yourself.

Deleting all conversations from the Messages app

Open the Messages app and look at the list of conversations. In the top left corner, tap the word "Edit" in blue text. Your phone will now show a small circle to the left of each conversation thread.

Tap the circle next to each conversation you want to delete, or tap "Select All" if it appears at the bottom of the screen. Once you've selected the conversations, a red "Delete" button will appear at the bottom right. Tap it, and your phone will ask you to confirm. Tap "Delete" again, and those conversations are gone.

This method works on iPhone 6 and newer. If you have hundreds of conversations, this can take several minutes. The process does not affect your photos, contacts, calendar, or any other data on your phone.

What happens to messages after you delete them

When you delete a conversation from your iPhone, the message thread disappears from your Messages app when ready. However, the actual data may linger on your phone's storage for a short time before being overwritten by new information. In practice, this means the messages are gone from your perspective—you cannot retrieve them through the Messages app or any iPhone setting.

Your wireless carrier (AT&T, Verizon, T-Mobile, etc.) may keep copies of text messages on their servers. The length of time varies by carrier and is usually between 3 months and 7 years, depending on their data retention policy. You cannot retrieve these copies yourself; only the carrier can access them, and only with a court order.

If you have iCloud backup turned on, and you deleted messages before your last backup, those messages are not in your backup. Restoring from that backup will not bring them back.

Factory reset: erasing your entire iPhone

A factory reset removes all data from your iPhone, including messages, photos, apps, contacts, and settings. This is useful if you're selling or donating your phone and want to may support nothing personal remains. Go to Settings, tap General, scroll down and tap Transfer or Reset, then tap Erase All Content and Settings.

Your phone will ask for your Apple ID password to confirm. This is a security feature—it prevents someone else from wiping your phone without permission. After you enter your password, the reset begins. The process takes 30 minutes to an hour depending on how much data is on your phone and your internet connection speed.

Once the reset is complete, your iPhone will look like a brand-new device. You can then set it up from scratch, restore from an iCloud backup (which will bring back your photos and apps but not deleted messages), or give it to someone else to set up.

Backing up before you delete

If you want to keep a record of your messages before deleting them, you can back up your iPhone to iCloud or to a computer using a Mac or Windows PC. On iCloud, go to Settings, tap your name at the top, tap iCloud, tap iCloud Backup, and tap Back Up Now. This creates a snapshot of your entire phone, including all messages, at that moment.

On a computer, connect your iPhone with a USB cable, open Finder (Mac) or iTunes (Windows), select your phone, and click Back Up Now. This backup is stored only on that computer, not in the cloud.

These backups are useful if you change your mind later or need to prove what a message said. However, they take up storage space—iCloud backups use your free 5 GB of iCloud storage, or you can pay for more. Computer backups use space on your hard drive.

Why you might want to delete messages

People delete messages for different reasons. Some want to free up storage space, though text messages take up very little room compared to photos or videos. Others delete messages for privacy—if you share your phone with family members or worry about someone accessing it, clearing conversations removes that risk. Some people delete messages as a regular habit, the way they might clear email, to keep their phone organized.

If you're concerned about privacy, deleting messages from your phone does not prevent your carrier or the person you messaged from having a copy. Only the person you messaged can delete their copy on their own device. If you want to prevent someone from seeing a message you sent, you cannot unsend it after it's been delivered (unless you use iMessage's "Unsend" feature, which works only within 2 minutes and only if both people have iOS 16 or newer).

Frequently Asked Questions

Can I delete messages from just one person without deleting everything?

Yes. Open Messages, find the conversation with that person, swipe left on it, and tap the trash icon. Or tap Edit, select just that conversation, and tap Delete. This removes only that thread, leaving all other conversations intact.

Will deleting messages free up a lot of storage space on my iPhone?

Not much. Text messages are tiny files—even 10,000 messages take up less than 1 MB of storage. If your iPhone is running low on space, deleting messages will not help much. Photos, videos, and apps use far more storage. Check Settings > General > iPhone Storage to see what's actually taking up room.

What's the difference between deleting a conversation and archiving it?

Deleting removes the conversation permanently. Archiving hides it from your main list but keeps it on your phone. You can archive a conversation by swiping left on it and tapping Archive. Archived messages still count toward your storage and can be searched, but they don't clutter your inbox.

If I delete messages, can the other person still see them?

Yes. Deleting a message from your iPhone only removes it from your phone. The person you messaged still has the message on their device unless they delete it themselves. There is no way to delete a message from someone else's phone after you've sent it, except with iMessage's Unsend feature within 2 minutes.

Do I need to delete messages before selling my iPhone?

You should do a factory reset instead. A factory reset is more thorough and removes all personal data at once. straightforward deleting the Messages app or individual conversations leaves other personal information on the phone. Go to Settings > General > Transfer or Reset > Erase All Content and Settings to wipe everything before handing over the phone.
