A system for monitoring embedded subscriber identity modules (eSIMs) is disclosed. The monitoring system provides visibility into the end-to-end performance of a mobile network operator (MNO) profile. The system controls a mobile device that is provisioned with a MNO profile and communicates with a subscription manager (SM) that produces and delivers the MNO profile. This system enables the monitoring of the interactions between the subscription manager and the eSIM and monitors the data preparation (SM-DP) and the secure routing (SM-SR) functionalities in the subscription manager.
