MOSX MDM and device identity

I discovered a small thing that can make life hard as an Apple device admin. When you enroll a Apple device that has a SIM card to a Apple Mobile Device Management server the server (or the device) uses the SIM card in it's identification. This can confuse the MDM server if for example a user switches device and put the same SIM card in the new device. The MDM server will not be able to distinguish the new device with the old SIM card (not even if you remove the old device) and report it as "New Device" and no pushing of profiles or info gathering works.

The solution is simple though. Before enrolling the SIM card equipped device pop out the SIM card. When the enrollment is finished you can pop back the card and everything works as expected.
