Profile Installation Failed: The new MDM payload does not match the old payload.

Description

This error is displayed on an 
iOS
 device during activation when a profile already exists on the device.

Possible solution

Go to 
Settings > General > Profiles
 on the device and verify that a profile already exists. Remove the profile and reactivate. If the issue persists, you might have to reset the device because data might be cached.
