Deactivating your iPhone is a simple process that can be done in a few easy steps. Whether you’re selling your phone, giving it to someone else, or just need to temporarily deactivate it, this guide will walk you through the process.

Deactivate iPhone Step by Step Tutorial

Before we get into the steps, it’s important to note that deactivating your iPhone will erase all content and settings, so make sure to back up any important data before proceeding. This tutorial will help you deactivate your iPhone so that it can no longer be used.

Step 1: Back up your iPhone

Back up all your data to iCloud or your computer before deactivating your iPhone.

Backing up your iPhone is crucial because once you deactivate your iPhone, all the data on the device will be erased permanently. If you have photos, videos, contacts, or any other important information on your iPhone, you’ll want to make sure it’s safely stored elsewhere before proceeding.

Step 2: Sign out of iCloud and iTunes & App Store

Go to Settings > [your name] > Sign Out. Enter your Apple ID password and tap Turn Off.

Signing out of your iCloud and iTunes & App Store accounts is an important step in deactivating your iPhone. This ensures that your personal information is no longer linked to the device and that the new owner or user won’t have access to your data.

Step 3: Erase all content and settings

Go to Settings > General > Reset > Erase All Content and Settings. Enter your passcode and confirm that you want to erase your iPhone.

Erasing all content and settings is the final step in deactivating your iPhone. This will restore the device to its original factory settings, removing all of your personal information, apps, and data.

After you’ve completed these steps, your iPhone will be deactivated and ready for a new owner or user. The device will be as good as new, and no one will be able to access your personal data.

Tips for Deactivate iPhone

  • Make sure to remember your Apple ID and password before starting the process.
  • If you’re selling your iPhone, consider including a note with the device that it has been properly deactivated.
  • After deactivating your iPhone, remove the device from your list of trusted devices in your Apple ID account settings.
  • If you have an Apple Watch paired with your iPhone, make sure to unpair it before deactivating the iPhone.
