How to Prepare an iPhone or Android Phone Before Selling It

Selling a phone should not start with the factory reset button.

Start by protecting your photos, messages, accounts, and mobile service.

Then remove the device from services that can keep it tied to you.

Only after that should you erase it and hand it over.

This guide explains how to prepare an iPhone or Android phone before selling it, with separate notes for Apple, Android, and Samsung devices where the steps differ.

The Outcome: A Phone Ready To Leave Your Hands

By the end, your old phone should no longer be your everyday device. Your important data should be backed up or transferred, your accounts should be removed, and the phone should be erased through the operating system’s reset tools.

That order matters. A reset can remove local data from the device, but it does not help if you forgot to transfer photos, left a SIM card inside, or kept the phone attached to an account lock.

The goal is practical: make the phone safer to sell, easier for the next owner to set up, and less likely to create a messy support problem after the sale.

Before You Start

Do these checks before you touch the erase button:

Keep the phone charged and connected to Wi-Fi.
Know the passcode, Apple ID password, Google Account password, or Samsung account details you may need.
Keep your new phone nearby if you are transferring data directly.
Decide whether you are moving a physical SIM, removing an eSIM, or asking your carrier for help.
Give yourself enough time for backups, transfers, sign-outs, and reset steps.

Apple’s own handoff guidance separates transfer, sign-out, Find My, and erase steps for iPhone owners. Google’s Android reset guidance also warns that a reset erases data from the phone, so backup comes first.

What You Need

You do not need special tools, but you do need access to the accounts connected to the phone.

For an iPhone, that usually means your Apple ID, iCloud settings, Find My status, and any SIM or eSIM details. Apple explains that Find My and Activation Lock are tied to Apple Account security, so signing out and removing the device properly matters before resale.

For Android, that usually means your Google Account, backup settings, screen lock, and any manufacturer account or service connected to the device. Google notes that Android menus can vary by device, so the exact path may differ between Pixel, Samsung, Motorola, OnePlus, and other brands.

Samsung owners should also check Samsung’s own reset and account guidance, because Galaxy phones can include Samsung-specific services in addition to Google services.

Step 1: Back Up Or Transfer Your Data

Start with the data you would miss if the phone disappeared today: photos, videos, messages, contacts, app data, authenticator access, notes, and downloaded files.

On iPhone, Apple provides transfer and backup guidance for moving data to a new iPhone or preparing a device before sale. Use Apple’s current instructions rather than relying on memory, because iCloud, Quick Start, and device-to-device migration options can change by iOS version.

On Android, use Google’s backup settings or the transfer flow offered during new phone setup. Google also provides Android backup guidance for photos, app data, contacts, and device settings, though exact options can vary by device and account setup.

If your photos matter most, do not assume they are backed up just because a cloud app is installed. Open your photo backup app and confirm that recent photos are actually present outside the old phone.

Step 2: Move Security And Login Access

Before erasing the phone, think about anything that helps you log in elsewhere.

That can include authenticator apps, banking app approvals, passkeys, two-factor prompts, password managers, work profiles, and recovery codes. Some services require you to move access while the old phone still works.

This is not the most exciting step, but it can prevent a bad surprise: losing the phone and then discovering it was also your only way into an important account.

Step 3: Sign Out Of iPhone Services Before Erasing

If you are selling an iPhone, follow Apple’s device-preparation guidance before erasing it.

Apple’s support instructions cover signing out of iCloud and media services, turning off Find My where required, removing the device from your Apple Account when appropriate, and then erasing the device. Apple also provides separate instructions for Activation Lock and what to do before giving away or trading in an iPhone.

Do not skip the Find My and Activation Lock part. If an iPhone remains tied to your Apple Account, the next owner may not be able to activate it normally.

A practical order is:

Confirm your data is backed up or transferred.
Unpair connected devices if needed, such as an Apple Watch.
Sign out of Apple services following Apple’s current instructions.
Turn off Find My or remove the device from your account where Apple’s flow requires it.
Erase the iPhone from Settings using Apple’s erase guidance.

Use Apple’s current support pages for the exact path on your iOS version, especially if the menus on your phone do not match older instructions.

Step 4: Remove Android Accounts And Factory Reset

For Android, the important idea is similar: back up first, remove accounts where appropriate, then reset.

Google’s Android factory reset instructions explain that a reset erases data from the phone and that you should know the Google Account information on the device before resetting. Google also notes that reset steps can vary by manufacturer and Android version.

A practical Android order is:

Confirm backup or transfer is complete.
Check that photos, contacts, and key app data exist outside the old phone.
Remove work profiles, manufacturer accounts, or payment cards if your device uses them.
Remove your Google Account where your device’s instructions recommend it before resale.
Use the phone’s factory reset option from Settings.

If you use a Samsung Galaxy phone, compare Google’s general Android guidance with Samsung’s support page for factory reset steps. Samsung’s menus and account services can differ from stock Android.

Step 5: Handle SIM, eSIM, And Storage Cards Carefully

Physical SIM cards are easy to forget. Before shipping or handing over the phone, open the SIM tray and remove your SIM card unless your carrier or trade-in process specifically tells you otherwise.

If the phone uses an eSIM, the right action can depend on the device, carrier, and whether you are moving service to another phone. Some reset flows offer options related to eSIMs, but there is no single Android path that fits every phone and carrier.

For iPhone, follow Apple’s current erase and transfer guidance for your situation. For Android, check your carrier and device instructions if mobile service is still active on the old phone.

If the Android phone has a microSD card, remove it before sale unless you intentionally plan to include it. A factory reset may not treat removable storage the same way as internal phone storage.

Step 6: Erase The Phone And Check The Setup Screen

Once backup, account removal, and service checks are done, erase the phone through its built-in reset tool.

On iPhone, use Apple’s erase instructions for iPhone, iPad, or iPod touch. The expected result is that the device returns to the setup screen instead of opening your old home screen.

On Android, use the factory reset option documented by Google or your manufacturer. After the reset, the phone should restart into its initial setup experience.

Do not sign back into your personal account after the reset just to test it. If you need to confirm that the phone powers on, stop at the setup screen and leave it ready for the next owner.

Step 7: Clean The Phone And Prepare The Sale

After the software reset, do a physical check.

Remove the case, wipe the phone gently, check the ports for obvious debris, and collect the charger, cable, box, or accessories you plan to include. Take clear photos of the actual phone for the listing, including any scratches or screen marks.

Be honest about condition, battery behavior, carrier lock status, and included accessories. That is better for the buyer and reduces the chance of a dispute later.

Troubleshooting: If Something Does Not Go Smoothly

If your backup is still running, do not reset the phone yet. Wait until the backup app or transfer tool shows that the data you care about is available somewhere else.

If an iPhone asks for Apple ID details, use Apple’s account and Activation Lock guidance. Do not sell the phone while it is still tied to your Apple Account.

If Android reset steps do not match your phone, use the manufacturer’s support page for that model. Google states that reset steps can vary, and Samsung publishes separate reset guidance for Galaxy devices.

If you cannot remove an account because you forgot a password, fix the account access problem before selling the device. Resetting first can make the handoff harder, not easier.

If the buyer says the phone is still locked after the sale, do not share your account password. Use Apple, Google, Samsung, carrier, or marketplace support instructions for account removal and proof-of-ownership steps.

Alternatives If You Are Not Ready To Sell

If you are unsure whether everything transferred, keep the old phone for a few more days on Wi-Fi before erasing it. That gives you time to check photos, contacts, documents, messaging history, and account access on the new device.

If the phone is damaged or will not power on, a normal backup-and-reset flow may not be possible. In that case, use official account dashboards and support channels to remove account links where available, then be clear with the buyer or recycler about the device condition.

If the phone is going to a trade-in program instead of a private buyer, read that program’s preparation instructions too. Trade-in programs may have specific packaging, lock-removal, and inspection requirements.

FAQ

Should I factory reset my phone before or after removing accounts?

Back up or transfer your data first, then handle account and lock-removal steps, then factory reset. That order reduces the chance of losing data or leaving the phone tied to your account.

Does a factory reset remove everything from an iPhone or Android phone?

A factory reset is the standard built-in erase step, but the exact behavior and preparation steps depend on the device. Follow Apple, Google, or manufacturer instructions before selling.

Do I need to remove my SIM card before selling my phone?

Yes, remove a physical SIM unless your carrier or trade-in program gives different instructions. For eSIM, check your carrier and device guidance before erasing or transferring service.

What should I do if the phone still asks for my Apple ID or Google Account?

Do not hand it over as ready for sale. Use official Apple, Google, Samsung, or manufacturer support guidance to remove the account link properly.

Can I sell the phone right after the reset screen appears?

If your data is backed up, your accounts are removed, your SIM or eSIM situation is handled, and the phone starts at the setup screen, it is generally ready for the buyer’s setup flow.
