To erase everything from your iPhone before selling it, follow these steps:
Back up your data – Use iCloud or MobiKin Assistant for iOS to save your photos, contacts, messages, and apps.
Sign out of iCloud and Apple ID – Go to Settings > [your name] > Sign Out. This disables Activation Lock.
Turn off Find My iPhone – In Settings > [your name] > Find My > Find My iPhone, switch it off.
Erase all content and settings – Go to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings. Confirm your choice.
Remove SIM card – Take out your SIM card before handing the device over.
After this, your iPhone will reset to factory settings, ready for a new owner.
