Deactivating an iPhone for sale means backing it up, signing out, erasing all content and settings, and removing account ties.
One missed step can leave an old iPhone tied to your Apple Account after it changes hands. Before a sale or trade-in, knowing how to deactivate an iPhone means handling four things: your data, your Apple Account, the cellular line, and services linked to your phone number.
Apple does not provide one Deactivate button. Turning the iPhone off or removing a SIM card does not erase personal data, sign out of your Apple Account, or prepare the phone for a new owner.
Deactivating An iPhone Before A Sale Or Trade
Deactivating an iPhone for another owner means removing your information and the account protections that could block the next person from setting it up. The handoff should end with the phone erased and showing the Hello setup screen.
If you plan to keep using the same iPhone, do not erase it merely to sign out. Current iOS versions let you sign out of your Apple Account without erasing the device, leaving most local data in place for a later sign-in.
Prepare The Phone Before Erasing Anything
Preparation protects the data you still need and prevents a rushed wipe from causing extra work. Finish transfers before you remove the old phone from service.
- Back up the iPhone to iCloud or a computer if you may need its photos, messages, settings, or app data later.
- Transfer to the new phone and confirm that needed photos, contacts, messages, and authentication apps arrived.
- Unpair an Apple Watch if one is paired with this iPhone.
- Move your cellular number to the replacement phone before deleting an eSIM when possible.
- Finish any pending repair shown in Parts and Service History before a trade-in.
A backup alone is not enough. The old iPhone still needs to be disconnected from your account and erased before another person receives it.
Sign Out And Erase The iPhone
The signed-out, erased state is what you want before a sale, trade-in, or gift. Finish the account sign-out and device wipe before the iPhone changes hands.
- Open Settings, tap [your name], scroll down, and tap Sign Out. On iOS 26 or later, choose Erase this iPhone if you are ready to wipe it now, or Sign Out But Don’t Erase if you still have another task to finish.
- If the phone was not erased from the sign-out screen, go to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings.
- Tap Continue. If the iPhone uses eSIM, choose whether to keep or delete it. For a phone leaving your possession, delete the eSIM after your number has been moved.
- Enter the iPhone passcode and Apple Account password when requested, confirm the erase, and let the reset finish.
Apple’s sell, give away, or trade in instructions confirm that erasing the iPhone turns off Find My and Activation Lock. The process is done when the iPhone restarts to the Hello screen. Your local data is gone, and the next owner can begin setup without your Activation Lock blocking them.
On iOS 18 or earlier, the sign-out screen may ask for your Apple Account password and then show Turn Off. The goal stays the same: sign out, then erase all content and settings.
What Does Deactivating An iPhone Actually Change?
Deactivating an iPhone changes several separate connections, not just the files stored on it. Find My, Activation Lock, the eSIM, and iMessage can each affect what happens after the phone leaves you.
| Item | Action | Result |
|---|---|---|
| Personal data | Erase All Content and Settings | Removes local apps, messages, photos, and settings. |
| iCloud data | Erase the iPhone instead of manually deleting synced items | Copies already stored in iCloud remain in your account. |
| Apple Account | Sign Out or complete the authenticated erase | The old phone stops being signed in to your account. |
| Find My | Complete the authorized erase | Find My turns off on the erased handoff device. |
| Activation Lock | Complete the authorized erase | A different Apple Account can activate the phone. |
| Apple Pay | Erase all content and settings | Payment cards are removed from that iPhone. |
| eSIM | Delete it during the erase when giving up the phone | The profile is removed; the carrier plan can stay active until canceled. |
| iMessage | Turn it off when moving to a non-Apple phone | The phone number is deregistered from iMessage. |
Handle The Phone Number And eSIM Separately
Erasing an iPhone does not cancel the cellular plan attached to its number. Deleting an eSIM removes the digital SIM profile from the device, while ending carrier service still requires the carrier.
If you are moving to Android or another non-Apple phone, deregister the number from iMessage before erasing the old iPhone. Open Settings > Apps > Messages and turn off iMessage, then go to Settings > Apps > FaceTime and turn off FaceTime.
Once the carrier line is active on the replacement phone and iMessage is off, carrier texts should go to that number on the new phone. If the old iPhone is already gone, Apple provides online iMessage deregistration.
Choose The Action That Matches Your Situation
The word deactivate can describe several different goals on an iPhone. Match the action to what you are actually trying to stop, remove, or transfer.
| Situation | Do This | Finished State |
|---|---|---|
| Selling | Back up, sign out, erase, delete eSIM | Hello screen; personal data removed |
| Trading in | Transfer data, finish pending repairs, sign out, erase | Ready for trade-in and setup |
| Giving it away | Back up, sign out, erase, remove cellular profile | Recipient can set up another Apple Account |
| Switching to Android | Transfer number, turn off iMessage and FaceTime, erase | Carrier messages go to the new phone |
| Keeping the iPhone | Use Sign Out But Don’t Erase if account sign-out is the only goal | Most local data stays on the phone |
| Already handed it off | Remote erase, then remove it from your account | New owner can activate it |
| Lost or stolen | Mark as lost, keep Find My enabled, contact carrier | Activation Lock keeps protecting the device |
| Canceling only service | Contact the carrier | Cellular service ends without erasing the iPhone |
What If You No Longer Have The iPhone?
An iPhone already sold or given away can still be erased remotely if it remains linked to your account. A lost or stolen iPhone needs different handling because removing it from your Apple Account too early also removes Activation Lock protection.
If you handed the phone to a known person, ask them to erase it from Settings. If that is not possible, use Find My on another Apple device or Find Devices at iCloud.com to erase it; after the erase completes, remove the device from your account so the new owner can activate it.
If the iPhone is lost or stolen, mark it as lost in Find My and contact the carrier if you want the line suspended. Do not turn off Find My merely to disable the phone. Find My lets you locate, lock, or remotely erase the device, and AppleCare theft-and-loss claims require Find My to stay enabled during the claim process.
Before The iPhone Leaves Your Hands
A complete handoff ends with the old iPhone empty, disconnected from your personal services, and ready for another Apple Account. Use this sequence while the phone is still with you.
- Back up anything you need to keep.
- Transfer your data and phone number.
- Unpair any Apple Watch connected to the old iPhone.
- Turn off iMessage and FaceTime if the number is moving to a non-Apple phone.
- Sign out of your Apple Account.
- Erase all content and settings, deleting the eSIM if the phone is leaving your possession.
- Wait for the Hello screen before handing it over.
If the Hello screen appears and setup does not ask for your Apple Account, the iPhone is ready for a new owner. Carrier service is separate, so cancel or transfer the line with your carrier when needed.
