Before handing over your iPhone, make sure your data is backed up and transferred to your replacement, finish any required repair, handle your SIM or eSIM, then sign out and erase the old device. Do not erase it until you have confirmed the new iPhone has what you need.

What should I do before trading in my iPhone?

Work through these steps while you still have the phone and can access your Apple Account. Menu names can vary by iOS version; follow the wording shown on your device and the instructions from your trade-in provider.

  1. Confirm account access. Make sure you know your Apple Account sign-in details and can receive verification codes at a trusted phone number. If your number will change, add another trusted number first. Apple explains account preparation in its pre-sale and trade-in checklist.
  2. Back up and transfer your data. Create a backup, set up the replacement iPhone, and check that your important data is there before erasing the old phone.
  3. Check repairs and linked devices. Review Parts and Service History, finish any repair marked “Finish Repair,” and unpair an Apple Watch if one is paired.
  4. Handle cellular service. Remove a physical SIM if the iPhone uses one. For an eSIM, arrange service suspension or transfer with your carrier.
  5. Sign out and erase. Once the transfer is confirmed, sign out of your Apple Account as appropriate for your iOS version, then erase all content and settings.
  6. Follow the handoff instructions. Use the trade-in provider’s packing and delivery instructions. Apple mail-in trade-ins use the supplied kit; do not include accessories the instructions say will not be returned.

How do I transfer everything to my new iPhone before erasing the old one?

Back up the current iPhone first, then complete setup and transfer on the replacement. Apple’s guidance describes Quick Start for iPhones running iOS 11 or later. For iOS 10 or earlier, it lists iCloud, iTunes, or Finder as backup and transfer options. Apple’s iPhone User Guide also describes temporary additional iCloud storage as an option when preparing to replace an iPhone. See Apple’s pre-transfer guidance and its iOS 27 iPhone User Guide.

Do not treat the start of a transfer as proof it is complete. Check the replacement for the data and access you rely on, including photos, contacts, messages, and app sign-ins, before wiping the old phone. Apple describes a backup as a way to copy and save information from an iPhone or iPad in its support instructions.

What should I check about repairs, Apple Watch, and messages?

Parts and Service History

Open Settings and check Parts and Service History if it is available for your iPhone. If a part is labeled “Finish Repair,” complete that repair before attempting a trade-in: Apple says an unfinished required repair prevents trade-in. Refer to Apple’s trade-in preparation instructions.

Apple Watch

If an Apple Watch is paired with the iPhone, unpair it before the phone leaves your possession. If you are also trading in a cellular Apple Watch, remove its active cellular plan as part of preparing that watch, following the carrier and trade-in instructions.

Switching to a non-Apple phone

If your replacement is an Android or another non-Apple phone, deregister iMessage so messages are no longer associated with the old Apple setup. Apple includes this as a conditional step in its trade-in and sale checklist.

Do I need to remove my SIM card before trading in my iPhone?

If your iPhone has a physical SIM card, remove it before handing the phone over. If it uses an eSIM, contact your wireless carrier to suspend service or arrange the transfer to your replacement; carrier procedures vary. During erasure, if the iPhone asks whether to erase the eSIM profile, choose that option when the device is being handed off. Apple covers SIM and eSIM preparation in its trade-in instructions and pre-sale checklist.

How do I erase my iPhone before selling it?

Erase the old iPhone only after the backup and transfer are complete. Sign out of your Apple Account and related services as appropriate for your iOS version, then use the current Settings path:

  1. Open Settings.
  2. Tap General.
  3. Tap Transfer or Reset iPhone.
  4. Tap Erase All Content and Settings and follow the prompts.
  5. If prompted on an eSIM iPhone, select the option to erase the eSIM profile when handing off the device.

Apple says erasing removes personal content from the device and turns off Find My and Activation Lock; it does not delete content stored in iCloud. Wording can differ by iOS release, so use the options displayed on the phone. Apple’s instructions for preparing an iPhone for sale or trade-in and iPhone User Guide provide the relevant steps.

What should I know about Apple mail-in trade-ins?

For an Apple mail-in trade-in, use the packing materials in the supplied kit and follow its instructions.
