Abstract
A method, apparatus, system, and computer program product for a secure subscriber identity module service. Communication via a mobile network is activated in response to receiving a request to activate communication service for the system by a secure partition of the system. In response to receiving the request, a key is retrieved for a permit service from storage accessible only by the secure partition. The key is included in a permit requesting to activate the communication service, and the permit is sent to a service provider for the communication service. The service provider communicates with the permit service to obtain a digital signature for the permit. The secure partition receives a signed permit from the service provider, confirms that the signed permit contains the digital signature by the permit service, and activates the communication service for the system in response to confirming that the signed permit contains the digital signature.
