    1

    Back up your data first

    ~25s
    Before erasing anything, make sure you have saved everything you want to keep. On iPhone: Settings → your name → iCloud → iCloud BackupBack Up Now. On Android: SettingsGoogleBackupBack Up Now. On Windows: use File History or copy important files to an external drive or cloud storage.

    Warning

    Once you factory reset a device, your data on that device is gone. Always verify your backup completed successfully before proceeding.

    2

    Sign out of all accounts

    ~25s
    On iPhone: go to Settings → tap your name → Sign Out. This removes your Apple ID from the device, disables Activation Lock, and allows the next owner to set it up fresh. On Android: SettingsAccounts → remove your Google account. On Windows: SettingsAccounts → sign out of Microsoft account.

    Quick Tip

    Signing out of your Apple ID is the most important step for iPhone. Without this, the next owner cannot activate the phone.

    3

    Factory reset the device

    ~18s
    iPhone: SettingsGeneralTransfer or Reset iPhoneErase All Content and Settings → follow prompts. Android: SettingsGeneral ManagementResetFactory Data ResetResetDelete All. Windows: SettingsSystemRecoveryReset This PCRemove EverythingCloud Download (thorough wipe).
    4

    Remove SIM card and memory card

    ~16s
    Use the SIM ejector tool (or a small paperclip) to pop out the SIM card tray. Keep your SIM card — it has your phone number. If your phone has a microSD card slot, remove that too. Your SIM goes into your new phone.
    5

    Price it and sell it safely

    ~24s
    Check eBay's "sold listings" for your exact phone model to see what it actually sold for recently. For safe in-person sales on Facebook Marketplace or Craigslist, meet in a public place (police stations often have designated safe-exchange zones). Accept payment via Venmo or cash — never accept checks or wire transfers.

    Quick Tip

    Quick Tip: Selling to official trade-in programs (Apple, Best Buy, Gazelle) gets you less money but eliminates all safety and logistics concerns.

    Selling an old phone, tablet, or laptop is a great way to offset the cost of a new one — and it keeps working electronics out of landfills. But if you hand over a device without properly erasing it first, you risk exposing photos, passwords, email accounts, banking apps, and personal documents to a stranger.

    The good news: all modern devices have a built-in factory reset that erases everything and restores the device to brand-new condition. Done correctly, a factory reset makes it impossible for the next owner to access your old data.

    Where to sell:

    Apple trade-in (apple.com/shop/trade-in) and Samsung trade-in programs are the simplest — no strangers, guaranteed payment. Best Buy, Target, and Gazelle also buy used devices. For more money, try eBay, Swappa, or Facebook Marketplace — but these require shipping or meeting a stranger, so take precautions.

    What you will get:

    A 2–3 year old iPhone might sell for $100–$300 depending on condition and model. Android phones vary widely. Laptops 2–4 years old can sell for $100–$400.

    Always back up your data before erasing. Remove SIM cards and SD cards. Charge the battery before selling.
