How can I find my lost phone when find my is off

If Find My was turned off, you won't see the phone's location on a map.

This leaves you with the old fashioned way of finding a lost phone: You go to places where you might have left it, and look for it. (If you think you'e close to it, you could try calling it from another phone and listening for ringing.)

If the phone was not merely lost, but stolen, then odds are that it's gone and you will never see it again.
