Subscriber-associated authentication, authorization and policy control information can be stored on a SIM (preprogrammed or user programmed), thereby facilitating grant or denial of access to services at an NIU while the programmed SIM or virtual SIM resides in the NIU. A provider can store a message in the SIM based on a payment, which determines the level and period of services to be provided. The SIM can be removed and used at any of a plurality of NIUs, thereby facilitating payment for the services following the SIM. |
