Abstract
A removable data store (34) for a mobile station (8) used in a mobile communications system, the data store being provided with two alternative fixed dialling number lists (70, 72) which are accessible by the mobile station. The data store itself determines a mode of operation of the mobile station, for example a telephone line mode, in order to select between accessing the first list or the second list. This allows the alternate list feature to be implemented without requiring the mobile station (8) to be modified for compatibility with the removable data store (34).
