For Android, detect SIM Card Swap by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed. Correlate Host Status via Android Enterprise DPC [DevicePolicyManager policy/compliance/security-state queries and SecurityLog events where supported]; System Settings via Android Enterprise DPC [DevicePolicyManager policy/compliance/security-state queries and SecurityLog events where supported]; User Account Authentication via Application Vetting / Identity Provider Telemetry [App authentication flow instrumentation or IdP sign-in/audit events]. Alert on a sequence or state change inconsistent with the device/app baseline, approved management policy, or expected user workflow; do not infer unobserved API calls, file/process activity, or payload content from management state alone.

For iOS, detect SIM Card Swap by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed. Correlate Host Status via Apple MDM [DeviceInformation / SecurityInfo / ProfileList / restrictions and compliance queries]; System Settings via Apple MDM [DeviceInformation / SecurityInfo / ProfileList / restrictions and compliance queries]; User Account Authentication via Application Vetting / Identity Provider Telemetry [App authentication flow instrumentation or IdP sign-in/audit events]. Alert on a sequence or state change inconsistent with the device/app baseline, approved management policy, or expected user workflow; do not infer unobserved API calls, file/process activity, or payload content from management state alone.
