1. An authentication bank comprising a plurality of physical identification modules, wherein a physical identification module includes 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 comprises instructions executable by at least one of the one or more processors for:
- receiving a first request for authentication information, wherein the first request was transmitted over a data channel, for associating a subscriber identity module (SIM) with a foreign wireless communication client or an extension unit, wherein the SIM is subscribed to a local carrier for a current location of the foreign wireless communication client or the extension unit, wherein the foreign wireless communication client or the extension unit is a wireless device not subscribed to the local carrier, and wherein the first request for authentication information comprises information regarding a second request for local authentication information received by the foreign wireless communication client or the extension unit from the local carrier over a local cellular communication network;
retrieving subscriber identity information and authentication information for the foreign wireless communication client or the extension unit from the SIM;
sending the subscriber identity information and the authentication information to the foreign wireless communication client or the extension unit over the data channel, wherein the data channel is distinct from local wireless services of the local carrier and wherein the authentication information for the foreign wireless communication client or the extension unit retrieved from the SIM is configured to be sent by the foreign wireless communication client or the extension unit to the local carrier over signal link of the local cellular communication network to provision a communication function from the local carrier for the foreign wireless communication client or the extension unit.

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.
