Abstract: A foreign wireless communication system is operated in a local communication network as if the foreign wireless communication system were a local wireless communication system. A data communication link is established between the wireless communication system and a service provider in a local wireless communication network. An outgoing request for authentication information is communicated from the wireless communication system to a remote administration system over the data communication link. The authentication information is received over the data communication link from the administration system and is transmitted over a signal link from the wireless communication system to the service provider. A requested wireless communication service is received at the wireless communication system based on authentication of the wireless communication system by the service provider using the authentication information.

Abstract: The mobile device stores a plurality of communication profiles comprising one or more local communication profiles and a global communication profile. The mobile device determines local access requirements for connecting to a local cellular network operator and determines whether the plurality of communication profiles comprises a local communication profile that satisfies the local access requirements. When the plurality of communication profiles does not comprise a local communication profile that satisfies the local access requirements: the mobile device connects to a global cellular network operator using the global communication profile; receives, from the global cellular network operator, a new local communication profile that satisfies the local access requirements and connects to the local cellular network operator using the new local communication profile.

Abstract: An authentication bank for a wireless communication system is disclosed. The authentication bank comprises a plurality of physical identification modules. A physical identification module may include one or more memory, processors, programs, and computer readable media storing subscriber identity module and authentication information. At least one of the one or more programs stored in the memory may comprise instructions executable by at least one of the one or more processors. The executable instructions may cause the one or more processors to receive a request, from an authentication server, for associating the subscriber identity module (SIM) with a foreign wireless communication client or an extension unit, retrieve subscriber identity information and authentication information for the foreign wireless communication client or the extension unit from the SIM, and send the subscriber identity information and the authentication information to the authentication server.
