With iOS 9.3 >, ZuluDesk can put a supervised device into Managed Lost Mode. Managed Lost Mode is a dedicated mode that you must disable before anyone can use the device again. Only ZMS can access device location information when the device is in Managed Lost Mode.
The user can’t unlock the device until you turn off Managed Lost Mode. The user is notified if anyone accessed location information during that time.
ZuluDesk can't control Lost Mode on unsupervised devices.
