A SIM for a mobile station used in a GSM mobile communications system, the SIM operating system being adapted to perform data coding format conversion for data items stored in the SIM and transmitted to the mobile station. This ensures that the SIM is able to receive, and present, data items in the required standard format at the interface between the mobile station and the SIM, whilst allowing the data items to be stored in a compressed format in the SIM memory, thereby increasing the perceived storage capacity of the SIM. |
