- locate your phone or tablet on a map in real time (if you think you left it somewhere),
- ring it at max volume (if it’s misplaced - yes, you could call it from another phone, but this will override ‘Silent’ or ‘Vibrate Only’ so it will ring , or
- erase it (if it's been stolen or is otherwise unrecoverable).
You can read the announcement or just go ahead and play with it.
