Abstract:
A request to initiate a performance of an operation on an embedded subscriber identity module (eSIM) profile stored in an embedded universal integrated circuit card (eUICC) of a machine-to-machine (M2M) device is sent from a backend service of a wireless communication carrier to a subscription management service. A callback message is then received at the backend service from the subscription management service indicating that the operation is performed on the eSIM profile, in which the callback message including an eUICC identifier (ID) of the eUICC or an Integrated Circuit Card identifier (ICCID) of the eSIM profile. A profile state entry of the eSIM profile is locate via the backend service in an eSIM profile state database. The profile state entry of the eSIM profile is then updated via the backend service in the eSIM profile state database with an updated profile state of the eSIM profile after the operation.
