How do I track my lost iPhone?

Please follow these instructions:

Find your lost iPhone or iPad - Apple Support

Be very careful with any messages that you may see claiming that your phone has been found and you just need to provide a few more details so the phone can be returned to you.

These are scams that are trying to trick you into providing your personal details and removing protection on your iPhone. Ignore and delete any messages like this that you might see.
