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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for mobile telephone roaming","description":"An authentication bank for a wireless communication system is disclosed.
