iPhone 7 Plus, iOS 13
if the phone is turned on and has an internet connection then
If you forgot the passcode on your iPhone, or your iPhone is disabled - Apple Support
if the phone is turned off or does not have an internet connection only option is to look manual for it
maybe report it lost or stolen to the police in your city and if you have insurance contact them.
