Earlier, I shared an article on how to download Find My iPhone app, which enables you to use any any iOS device to find your iOS device and protect its data if stolen or misplaced. If you don’t have any iOS device to use, you can also make use of the Find My iPhone website.
You can access the Find My iPhone online page on a Mac or PC via : www.icloud.com/find
Right there, sign in with your Apple ID (the one you use with iCloud) to locate your missing device on a map, remotely lock it, play a sound, display a message, or erase all the data on it.
