How to find my lost iPhone

Start here: If your iPhone, iPad, or iPod touch is lost or stolen - Apple Support

Sorry your phone has been misplaced.

However, only YOU can locate your device using FindMy.

See how here:

Find My - Official Apple Support

HOWEVER, if you suspect that your phone has actually been stolen, see this:

If your iPhone, iPad, or iPod touch is lost or stolen - Apple Support

Note too that thieves will almost always prevent you from finding your phone w/ FindMy.
