A data adapter (2) for a mobile telephone (1) of the type intended to have a subscriber identity module (SIM) inserted therein and capable of supporting a short message service (SMS). The adapter includes means for coupling to the telephone so that data can be transferred therebetween. The coupling means includes a connector configured as a standard SIM, i.e. designed to fit in the SIM interface (3) of the telephone (1). The adapter itself includes means (6,7) for receiving a SIM such that data can be read from or written to the SIM. Means are included in the adapter for converting received data into SMS format thereby enabling the mobile telephone to be used for receiving/transmitting data messages other than normal SMS messages. A data input/output (8) may be provided on the adapter for connection to an external data terminal, e.g. a PC.
