iPhone 8 unavailable

iPhone 8 Plus, iOS 15
If you forgot your passcode, you can use your Apple ID and password to erase and reset your device without a computer.
If you enter the wrong passcode on your iPhone Lock Screen too many times, an alert lets you know that your iPhone is disabled. (Learn what to do if you see "[Device] unavailable" or "Security Lockout" on your iPhone or iPad.)
