Before selling or giving away your phone, wiping it ensures that personal data—such as photos, contacts, messages, and account credentials—cannot be accessed by the new owner. A proper wipe protects privacy and prevents identity theft.
Steps to Prepare Your Phone
1. Backup Your Data
-
Use cloud services or external storage to save contacts, photos, and app data.
-
Ensure that important information is safely stored before wiping the device.
2. Sign Out of Accounts
-
Sign out of Google, Apple ID, or any other accounts linked to your phone.
-
Remove all synced accounts to prevent the new owner from accessing your data.
3. Remove SIM and SD Cards
-
Take out your SIM card and any external storage to avoid leaving personal information behind.
