Abstract
Abstract 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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
126 words
A data adapter for connection to a radiotelephone, said radiotelephone having first receiving means for removably receiving a Subscriber Identity Module (SIM) to enable information to be transferred between the radiotelephone and a SIM present in the receiving means, the data adapter comprising: means for coupling the data adapter to the first receiving means in said radiotelephone to enable data to be transferred between the telephone and the data adapter, the means for coupling including a connector adapted to mate with the first receiving means in said radiotelephone; second receiving means in said data adapter for removably receiving a SIM card to enable data to be transferred between said SIM card and the means for coupling; and means for processing data transferred to the data adapter.
Claim 2
Dependent Claim
126 words
A data adapter for connection to a radiotelephone, said radiotelephone having first receiving means for removably receiving a Subscriber Identity Module (SIM) to enable information to be transferred between the radiotelephone and a SIM present in the receiving means, the data adapter comprising: means for coupling the data adapter to the first receiving means in said radiotelephone to enable data to be transferred between the telephone and the data adapter, the means for coupling including a connector adapted to mate with the first receiving means in said radiotelephone; second receiving means in said data adapter for removably receiving a SIM card to enable data to be transferred between said SIM card and the means for coupling; and means for processing data transferred to the data adapter.
Claim 3
Dependent Claim
