How to Sell Your Old Phone Without Exposing Personal Data
Removing the SIM is not enough to prepare a phone for a new owner.
The aim is to help you complete one clear task, recognize what needs verification, and avoid the most common mistakes. Work through the checks in order, then use the real-world example to apply them to your situation.
This guide is designed as a practical decision checklist. Use the relevant official guidance alongside the steps, especially when rules depend on your country, device or individual circumstances.
1. Back up what you will need
Copy photos, contacts, messages and authentication recovery methods before touching the reset controls. Confirm that important files actually open on a second device or trusted backup. Check whether banking and authenticator apps have transfer steps that must occur before wiping.
2. Disconnect accounts and accessories
Unpair watches and other accessories. Sign out of accounts and remove device-management profiles according to the manufacturer instructions. Check for account-activation protections that could prevent the next owner from setting up the device even after a reset.
3. Reset through the official settings
Remove physical memory cards that you intend to keep, then run the supported factory reset from Settings. Keep the device charged and allow the process to complete. A factory reset is different from deleting a few photos and cannot be substituted by clearing the home screen.
4. Confirm the handover condition
Restart the phone and verify it reaches its initial setup screen without requesting your account credentials. Give an accurate description of battery health, damage and included accessories. Avoid sending a buyer screenshots that show your cloud accounts, notifications or personal identifiers.
