Don’t panic. If one of your Apple devices goes missing, iCloud can help you figure out where it is. Just sign in at
iCloud.com or use the Find My iPhone app to see your missing iPhone, iPad, iPod touch, or Mac on a map. And with the Lost Mode feature you don’t just see where your device is, you can track where it’s been. That way you can decide on your best course of action. You can immediately lock your device and send it a message with a contact number. Then whoever finds it can call you from the Lock screen without accessing the rest of the information on your device.
