A method and apparatus are disclosed for performing secure remote subscription management. Secure remote subscription management may include providing the Wireless Transmit/Receive Unit (WTRU) with a connectivity identifier, such as a Provisional Connectivity Identifier (PCID), which may be used to establish an initial network connection to an Initial Connectivity Operator (ICO) for initial secure remote registration, provisioning, and activation. A connection to the ICO may be used to remotely provision the WTRU with credentials associated with the Selected Home Operator (SHO). A credential, such as a cryptographic keyset, which may be included in the Trusted Physical Unit (TPU), may be allocated to the SHO and may be activated. The WTRU may establish a network connection to the SHO and may receive services using the remotely managed credentials. Secure remote subscription management may be repeated to associate the WTRU with another SHO.
