Why This Checklist Matters Before You Let Go

Handing off an old phone feels simple — you're just passing on a piece of hardware. But that device holds far more than you might realize: saved passwords, payment methods, logged-in accounts, private messages, and sometimes years of photos. Skipping even one step in the handoff process can expose your personal data to a stranger or create a headache for the person receiving the device.

This checklist walks you through every action worth taking before your phone changes hands, whether you're gifting it to a family member, trading it in, or selling it privately. Each step is designed to protect your privacy, make the device genuinely usable for its next owner, and keep you from paying for services tied to a phone you no longer own.

Don't Skip the Account Sign-Out Step

On iPhones, leaving your Apple ID active before a factory reset keeps Activation Lock in place — meaning the next user cannot set up the device at all. On Android, a linked Google account can similarly trigger Factory Reset Protection, requiring your original credentials to unlock. Always sign out of your primary account first, then reset.

A Factory Reset May Not Erase Everything on Older Phones

On Android devices running software older than Android 6, a factory reset does not always overwrite storage completely, and data-recovery tools can sometimes retrieve remnants of old files. Enabling full-disk encryption before the reset scrambles that data, making recovery practically impossible. This is less of a concern on modern iPhones and newer Android devices, which use hardware-level encryption by default.

If you're on the receiving end of a secondhand device — particularly a computer — our guide to checking a used or refurbished computer covers what to look for before you commit.

How to Work Through the Checklist

Work through the groups in order — backing up first, then signing out, then physically removing components, and finally resetting. Jumping straight to the factory reset without signing out of your accounts first is the single most common mistake, and it can render the phone unusable for whoever receives it.

Back Up Your Data

Back up photos, videos, and documents to a cloud service or computer before doing anything else. Must
Sync your contacts and calendar to your account (Google, Apple ID, or Microsoft) so they transfer to your next device. Must
Export or note any app data — such as saved game progress or authenticator app codes — that won't automatically carry over. Should

Sign Out of Accounts

Sign out of your Apple ID (iPhone) or Google account (Android) from the device's Settings — this disables Activation Lock and Find My Device. Must
Log out of banking, shopping, and email apps individually before the factory reset as an added precaution. Should
On iPhones, go to Settings > Messages > Send & Receive and deregister your phone number from iMessage to avoid missing future texts. Must
Sign out of any streaming services (such as music or video apps) to free up device-authorization slots, since many platforms limit the number of authorized devices. Should

Remove Physical Items

Eject and keep your SIM card — the next owner will need their own, and yours contains carrier account data. Must
Remove any microSD or memory card and transfer its contents to your new device or a computer. Must
Remove any phone case, screen protector, or accessories you want to keep before handing the device over. Nice to have

Encrypt and Factory Reset

On older Android devices (Android 5 or earlier), enable full-disk encryption in Settings > Security before performing the factory reset to make deleted data harder to recover. Should
Perform a factory reset through the phone's Settings menu (usually under General Management or System > Reset Options), not a third-party app. Must
After the reset completes, confirm the setup screen appears — this confirms the device is fully wiped and Activation Lock is cleared. Must

Final Checks Before Handoff

Charge the phone to at least 50% so the recipient can power it on and verify everything works immediately. Nice to have
Gather original accessories — charging cable, adapter, original box — to increase the device's value if selling. Nice to have
Check your carrier account to remove the device from your plan or transfer ownership if required. Should
Notify your insurance provider to remove the device from your policy so you're not paying premiums on a phone you no longer own. Should
If selling, document the phone's condition with photos before handing it over to protect yourself in any disputes. Should

Once you've handed off the device, it's worth reviewing what's connected to your phone number at the carrier level. If you're planning to use a new SIM or travel internationally, see our overview of SIM cards, eSIMs, and international phone plans for what to think about next.

iMessage Must Be Turned Off Separately

If you're moving from an iPhone to an Android device and forget to deregister your number from iMessage, texts from other iPhone users may continue routing to the old Apple device rather than your new phone. You can deregister your number directly through Apple's online support tool even after you've already wiped the phone. This step is separate from the factory reset and is easy to overlook.
