An enrolled iPad needed a carrier APN profile to activate cellular service. The APN profile was provided as a file from the carrier, so the plan was to download it on the iPad, open it, and install it manually.
When the Hexnode policy was applied, iPadOS showed that profile installation through the UI was disabled. I then enabled the restriction setting that allows installing configuration profiles, but the manual install still failed with another profile installation error.
The only workaround that worked was removing the Hexnode policy, installing the carrier APN profile manually, and then pushing the policy back to the iPad. Is there a better way to handle carrier APN profiles without removing the MDM policy each time?
