User did out of box setup on an iPhone12 and then realized that it gave her a new number.

She wants to keep her old number.

    Thanks for posting your question in the Microsoft Q&A forum.

    The phone number in Intune does not auto-update after a SIM/number change and cannot be edited. To update it, the device must be wiped and re-enrolled.

    • Remove the device from Intune.
    • Insert the new SIM/number.
    • Factory reset the iPhone.
    • Re-enroll via the Company Portal.

    If the number is used for MFA, update it separately in Azure AD security info.
