How to Wipe Your Phone Before Selling It, in the Right Order

Wipe your phone before selling: the order matters

Selling or trading in a phone feels simple until the buyer tells you the device still asks for your password. That happens when you erase a phone without removing your account first, and it is the single most common reason a phone sale falls through. This guide to wipe your phone before selling covers the right order for iPhone, Pixel, and Samsung, plus the steps people forget: authenticator apps, eSIMs, and the checks to run after the erase.

The core idea is short. A factory reset erases your data, but it does not remove the anti-theft lock that ties the phone to you. Apple calls it Activation Lock. Android calls it Factory Reset Protection. Both survive a wipe unless you remove your account first. Erase in the wrong order and the phone boots up demanding your credentials, and the new owner cannot get past the setup screen. Erase in the right order and the buyer gets a clean phone that sets up like new.

Step 1: back up, then verify the backup

Back up before you touch anything else. On iPhone, go to Settings, tap your name, then iCloud, then iCloud Backup, and tap Back Up Now. Wait for it to finish; a backup that is still running when you erase is no backup at all. On Android, go to Settings, System, Backup, and confirm Google Backup is on, then run a backup manually. If you use a computer, an encrypted local backup preserves passwords and health data that a cloud backup may not.

Then verify it, because a backup you have not checked is only a hope. Open your new phone or the cloud service and confirm that recent photos, contacts, and messages are actually there. Check one conversation thread and one recent photo, not just the backup timestamp. If anything is missing, fix it now, while the old phone still has the originals.

Step 2: move the access tied to your old phone

This is the step most guides skip, and it causes the most pain. Authenticator apps do not always move with a cloud backup. Open each authenticator app and transfer accounts to the new phone, or temporarily switch those accounts to another second factor, before you erase. Banking apps, workplace apps, and password managers may also need reactivation on the new device. Do this while both phones are in your hands.

Unpair your watch and accessories next, and remove cards from the phone's wallet. On iPhone, unpairing Apple Watch from the Watch app also removes Activation Lock from the watch itself, which matters if you plan to sell it too. On Android, remove any smartwatch pairing and delete saved payment methods. These are small steps, but each one is a locked door you will not be able to open after the erase.

Step 3: remove accounts and locks, then erase

On iPhone, sign out of your Apple Account first (Settings, your name, Sign Out), turn off Find My, and then go to Settings, General, Transfer or Reset iPhone, Erase All Content and Settings. On a Pixel, remove your Google account first, then go to Settings, System, Reset options, Erase all data (factory reset). On a Samsung Galaxy, remove your Google and Samsung accounts, then go to Settings, General management, Reset, Factory data reset.

Two practical notes. Google advises charging an Android phone to at least 70 percent and waiting 24 hours after changing your Google password before resetting, to avoid triggering a lock. And take out the physical SIM and microSD card before you hand the phone over. For eSIMs, decide whether to transfer the plan to your new phone or delete it, following your carrier's instructions, since a deleted eSIM cannot be recovered from the old device.

Step 4: check the welcome screen, and the after-sale fixes

After the erase finishes, the phone should show the welcome screen and invite a fresh setup. Do not set it up again yourself. Confirm it does not ask for your previous credentials. If it does, the account removal did not complete, and you need to fix it before selling. A phone that passes this check is ready to hand over.

If the phone already left your hands and you forgot a step, you can still fix most problems remotely. Remove the device from your Apple Account at apple.com or from your Google Account's device list, which releases the activation lock. Change passwords for any service that was signed in on the phone, and review active sessions in your Google and Apple accounts. This is not as clean as doing it beforehand, but it protects your data and unblocks the buyer.

One last tip: the same discipline applies to the phone you are keeping. If your old phone is staying in a drawer as a backup, it still holds your accounts and data, so wipe it too or keep it secured. And if you are buying a used phone rather than selling one, run the checks in our phone theft protection guide before you pay, and confirm the device still gets updates with our phone security update check. A clean, unlocked, updated phone is the only kind worth buying secondhand.
