Abstract: Aspects of the subject disclosure may include, for example, a system that provides a first message to a communication device that includes a temporary international mobile subscriber identity (IMSI) to be provisioned onto the device. A first registration message is sent to a registration function server, wherein the server includes a registry, wherein the first registration message indicates to the server to add the temporary IMSI to the registry. A second registration message is sent to the server in response to detecting expiration of a limited time period, wherein the second registration message indicates to the server to remove the temporary IMSI from the registry. A second message is provided to the wireless communication device that indicates to the wireless communication device the expiration of the limited time period, and that the temporary IMSI is removed from the registry of the registration function server. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, a system that manages utilization of mobile subscriber identity information including enabling reuse of such information by a different communication device and/or re-authorizing use by a communication device that previously was authorized to utilize the information. The reassignment of mobile subscriber identity information can be based on detecting a registration that utilizes a bootstrap mobile subscriber identity information or a registration based on a mobile subscriber identity information that the network has designated not for use by the particular communication device. Other embodiments are disclosed.

Abstract: A system that incorporates the subject disclosure may include, for example, instructions which when executed cause a device processor to perform operations comprising sending a service request to a remote management server; receiving from the management server an authentication management function and an encryption key generator for execution by a secure element and an encryption engine for execution by a secure device processor, sending a request to establish a communication session with a remote device; and communicating with the remote device via a channel established using an application server. The secure element and the secure device processor authenticate each other using a mutual authentication keyset. The secure element, the secure device processor and the device processor each have a security level associated therewith; the security level associated with the secure device processor is intermediate between that of the secure element and that of the device processor. Other embodiments are disclosed.
