MDM stands for Mobile Device Management. When a business or educational institution purchases a batch of devices from Apple, they can sometimes enrol in a program which allows them to add restrictions to all their devices and essentialy have authority over them all. With MDM active on your device, you won't be able to activate it without permission from the supervising authority. Therefore, checking the MDM status has become just as essential as the Find My iPhone status.
