Check Content

Determine if the site authorizing official (AO) has approved the use of eSIM transfer. Look for documentation of AO approval. If eSIM transfer is not approved, review configuration settings to confirm it is disabled. If approved, this requirement is not applicable. This a supervised-only control. If the iPhone or iPad being reviewed is not supervised by the MDM, this control is automatically a finding. If the iPhone or iPad being reviewed is supervised by the MDM, follow these procedures: This check procedure is performed on both the device management tool and the iPhone and iPad device. Note: If an organization has multiple configuration profiles, the check procedure must be performed on the relevant configuration profiles applicable to the scope of the review. In the iOS/iPadOS management tool, verify "Allow outgoing eSIM transfers" is unchecked. On the iPhone/iPad device: 1. Open the Settings app. 2. Tap "General". 3. Tap "VPN & Device Management". 4. Tap the Configuration Profile from the iOS management tool containing the restrictions policy. 5. Tap "Restrictions". 6. Verify "Outgoing eSIM transfers not allowed" is listed. If the AO has not approved eSIM transfers and "Allow eSIM outgoing transfers" is listed in the management tool or "Outgoing eSIM transfers not allowed" is not listed on the Apple device, this is a finding.

Fix Text

Install a configuration profile to disable the transfer of an eSIM from one DOD phone to another unless the service has been approved by the AO. This a supervised-only control.
