Selling an old phone is a great way to get value from a device you no longer need. But before you hand your phone over to a buyer, there is one important job to complete: prepare it properly.
Your phone may contain personal photos, messages, contacts, emails, saved accounts and other private information. Simply removing a few apps is not enough. You also need to make sure your important data has been backed up and that your accounts and personal information are no longer connected to the device.
Whether you’re selling an iPhone, Samsung Galaxy, Google Pixel or another smartphone, this checklist will help you prepare your phone for sale safely and confidently.
Quick Checklist Before Selling Your Phone
Before you sell your phone, make sure you have:
- Backed up important data
- Checked that your backup is complete
- Transferred important information to your new phone
- Checked your photos, contacts and messages
- Moved any files stored only on the old device
- Signed out of relevant accounts
- Disabled device-tracking features where required
- Removed your SIM card or transferred your eSIM
- Unpaired connected accessories
- Checked the phone’s condition
- Cleaned the device carefully
- Performed a factory reset
- Confirmed the phone starts at its setup screen
- Gathered any accessories you still have
Now let’s go through each step.
1. Don’t Reset Your Phone Until Your Data Is Safe
The biggest mistake you can make is erasing your phone before checking that your important information is somewhere safe.
Think about everything you use your phone for every day. Your device may contain years of photos, contacts, messages, notes, documents and other files.
Before you reset anything, create a backup using the appropriate service for your device.
For Android phones, Google provides a backup option through the device settings, although the information that can be restored can vary between apps.
For iPhone, Apple recommends backing up your information before preparing the device for sale or trade-in.
Check these before moving on:
- Photos and videos
- Contacts
- Messages
- Notes
- Calendar information
- Documents
- Important app data
- WhatsApp or other messaging data
- Passwords and authentication information you need to transfer
2. Check Your New Phone Before Erasing the Old One
If you’re selling your old phone because you’ve upgraded, don’t immediately wipe the old device.
First, check your new phone.
Open your photos, contacts, messages and other important apps. Make sure the information you expected to transfer is actually available.
This extra check can save you from discovering after the reset that an important file or photo was still stored only on your old phone.
Once you are satisfied that your important information is accessible on your new device or safely backed up, you can prepare the old phone for sale.
3. Look for Data That May Not Be in Your Main Backup
A standard phone backup may not include everything you have stored on your device.
Take a few minutes to look through your phone for files that you may have forgotten about.
Check folders such as:
- Downloads
- Documents
- Voice recordings
- Offline files
- Camera folders
- Screenshots
- Files saved by individual apps
This is particularly useful if you’ve owned the phone for several years.
Google notes that not all Android apps can back up or restore every type of data, so checking important apps individually is worthwhile.
4. Make Sure Your Accounts Are No Longer Tied to the Phone
Your phone may be connected to accounts that you still use on your new device.
Before selling, review the accounts associated with the phone and follow the manufacturer’s instructions for removing them.
This may include:
- Apple Account
- Google Account
- Samsung account
- Email accounts
- Payment services
- Other accounts linked to the device
This step is important not only for privacy but also to help the next owner set up the phone without encountering account or activation restrictions.
For iPhone users, Apple specifically recommends signing out and following its preparation process before selling or giving away the device.
5. Turn Off Device-Tracking and Activation Features
Some phones have security features designed to prevent unauthorised use if the device is lost or stolen.
Those features can also affect the next owner if they are still linked to your account.
For an iPhone, Apple advises turning off Find My before selling, giving away or trading in the device.
Android devices can have their own account and device-protection systems, so follow the instructions for your particular manufacturer and model.
If you’re unsure which security feature applies to your phone, check the manufacturer’s official support instructions before resetting it.
6. Transfer or Remove Your SIM
Don’t forget about your mobile connection.
If your phone uses a physical SIM card, remove it before handing the phone over.
If you’re using an eSIM, transfer your mobile service to your new phone and follow your carrier’s instructions to remove or transfer the eSIM.
Your phone may look completely reset while your mobile service remains linked to it, so check this before the sale.
7. Disconnect Your Accessories
Your old phone may still be paired with other devices.
Before selling it, check for connections to things such as:
- Smartwatches
- Wireless earbuds
- Bluetooth headphones
- Cars
- Speakers
- Other Bluetooth accessories
Unpair devices you no longer need connected to the old phone.
This also makes it easier to connect those accessories to your new phone.
8. Check the Phone Before You Hand It Over
Once your personal information is safely backed up, inspect the physical device.
Check the:
- Screen
- Camera lenses
- Buttons
- Charging port
- Speakers
- Microphone
- Cameras
- Battery performance
- Wi-Fi
- Bluetooth
- Mobile connection
If something isn’t working correctly, make a note of it.
Being accurate about your phone’s condition is important when requesting a valuation or selling the device.
If your phone has a cracked screen, battery issue or another fault, don’t automatically assume it has no value. Depending on the model and condition, damaged phones may still be suitable for resale, repair or parts.

9. Give Your Phone a Safe Clean
Your phone doesn’t need to look brand new, but cleaning it before selling is a simple way to present it properly.
Use a soft, suitable cloth to remove fingerprints and surface dirt from the screen and exterior.
Pay attention to areas such as:
- Screen
- Camera lenses
- Back panel
- Buttons
- Exterior surfaces
Avoid forcing objects into ports or using excessive liquid.
The goal is simply to remove normal dirt and fingerprints without damaging the device.
10. Don’t Forget About Your Phone’s Storage
Before you reset the device, check whether you have anything stored locally that you still need.
This can include:
- Downloaded documents
- Photos
- Videos
- Recordings
- Screenshots
- Files transferred from a computer
Cloud storage can make it easy to forget about files that were saved directly to the phone.
If you need something, move it somewhere safe before continuing.
11. Factory Reset the Phone
After you back up your important information and complete the account and connection checks, you can erase the phone.
A factory reset removes the information and settings stored on the device and returns it to a setup state.
For an iPhone, Apple’s current instructions use:
Settings → General → Transfer or Reset iPhone → Erase All Content and Settings.
For Android, the exact menu can vary by manufacturer and software version. Google provides factory-reset instructions and recommends checking manufacturer-specific guidance if the steps differ on your device.
Important: Do not rely on deleting individual photos, messages or apps instead of performing the proper reset process.
12. Check the Phone After the Reset
Your final privacy check is simple but important.
Turn the phone on after the reset.
You should see the initial setup experience rather than your old home screen, photos, messages or personal accounts.
For example, Apple notes that after an iPhone is properly erased, it restarts and displays the setup screen.
If you can still access your personal information, stop and complete the appropriate reset process before selling the device.
13. Keep Any Accessories You Already Have
If you still have the original box, charging cable or other compatible accessories, keep them together.
You don’t need to buy new accessories just to prepare an old phone for sale.
Simply gather the items you already have so you know what is included with the device.
14. Record Your Phone Details Before Sending It
Before handing over your device, keep a private record of the phone’s key details.
This can include:
- Exact model
- Storage capacity
- Colour
- IMEI
- Serial number
Don’t publish sensitive device identifiers publicly in an online listing.
Having accurate information available can also make the selling or valuation process easier.
What Not to Do Before Selling Your Phone
Preparing your phone is not just about completing the right steps. It’s also about avoiding common mistakes.
- Don’t erase the phone before backing it up – Once the device has been reset, information that wasn’t backed up may be difficult or impossible to recover.
- Don’t assume every app is backed up – Some apps handle their own data differently. Check important apps before resetting the phone.
- Don’t leave your accounts connected – A reset should be part of a complete preparation process that includes dealing with the accounts and security features associated with your device.
- Don’t forget your SIM – Check whether you have a physical SIM or eSIM before handing over the phone.
- Don’t hide damage – If you’re getting a valuation, provide accurate information about the phone’s condition. This helps avoid surprises during the assessment.
