Managed Lost Mode
Mobile device management (MDM) solutions work with Lost Mode on iCloud.com to locate supervised devices when they are lost or stolen. MDM solutions can remotely place a supervised device in Lost Mode (called Managed Lost Mode). When an MDM solution remotely enables Managed Lost Mode, the device is locked and a message can be displayed with a phone number and other information on the Lock screen. Also, when a device is in Managed Lost Mode, an MDM solution can remotely query for the device’s location.
If the MDM solution remotely disables Managed Lost Mode, the device will be unlocked and the user will be notified that Managed Lost Mode was enabled and the device’s location was collected by the MDM solution upon unlocking the screen. Managed Lost Mode doesn’t require Find My iPhone to be enabled.
