Abstract
A host processing apparatus () and a user removable memory () are disclosed. The host processing apparatus () and the user removable memory () are, in use, connected to one another by respective connectors. The user removable memory () is provided in the form of a secure digital (SD) memory card with an expanded subscriber identity module (SIM) function. The host processing apparatus () is configured to convert SIM-related request signals to file access signals which identify a location or locations on the user removable memory () and one or more file access functions. The file access signals are transferred to the user removable memory () via the connectors. The user removable memory () comprises a flash memory (), a SIM () programmed with data associated with a communications system, and interface means () for receiving the file access signals from the host processing apparatus (), and configured to identify from the location(s) therein whether a memory or SIM function is to be applied. If the latter, the received file access function(s) are converted to SIM function(s) which are applied to the SIM () for transferring results back to the host processing apparatus ().
