A card reader 9 is loaded with a card which saves units of call credit. The card is capable of holding the telephone number of desired party registered by means of a controller circuit 16. For making a call, the telephone number is read out from the card and used in a dialing circuit 3 for automatic dialing. During the call, the call credit units are counted down according to a charge list for the party. Also, a language used for display on a liquid crystal display 8 and an amplitude of volume adjusted in the call may be registered in the card. When the call credit units are less than a reference level, a message of demanding the loading of a new card appears on the display 8. As the new card is loaded in place of the current card, the call can be continued without interruption. At the time, relevant data including the telephone number of party to be called and the displayed language are automatically transferred from the current card to the new card. Accordingly, the automatic dialing is implemented for calling and communicating with a desired party without the use of an extra facility at a local station. <IMAGE> |
