How do I unlock my iphone?

Hi

Is it locked from incorrect screen pass code (disabled), then see:

Note - your phone will be wiped. You can restore it if you have a backup.

If it is activation locked

If it is simlocked

You will need to restore the phone using a computer and the process will erase the device. Instructions here...

If you forgot the passcode on your iPhone, or your iPhone is disabled - Apple Support
