If you are referring to a lost or stolen phone, the only way to attempt to locate the device is if you had activated Find My iPhone in the iCloud section. Then you can log into iCloud and try to locate the device. If the device has been turned off or restored, then you will not be able to locate it. Apple does not locate iPhones.
