What does iPhone Unavailable mean on iPhone 15

Actually, there are many situations where an iPhone 15 will become unavailable, such as forgetting iPhone 15 passcode, trying wrong passcode multiple times, or being pranked by others. Once you enter the wrong password five times in a row, the screen will say "iPhone Unavailable, try again in 1 minute", which is a security measure developed by Apple to prohibit others from having access to your device, even if by brute force.

Except for emergency calls, you cannot view or modify any data and settings of a disabled iPhone. And if you continue to make incorrect passcode attempts, the waiting time will keep increasing. To break this deadlock, you can only reset your iPhone 15 to itself factory settings.

The iPhone Unavailable appears along with a Forgot Passcode? option in iPhone 15 when upgrading to iOS 17 and later. But this option on devices running from iOS 15.2 to iOS 16.7.2 is called Erase iPhone. The Forgot Passcode? option can erase your device when your iPhone 15 is unavailable, allowing you to unlock iPhone 15 without passcode.

In addition to this, there is an iPhone Reset feature in Forgot Passcode? that lets you get back into your unavailable iPhone 15 with your old passcode within 72 hours of a passcode change.
