If it is determined in step S51 that a new card has been inserted, "Omachikudasai" is displayed in step S52, and in step S53, it is determined whether the new card is a normal card or an abnormal card. If it is determined that the card is a normal card, the process proceeds to step S54, and the card information stored in the internal memory in step S46 is written to the new card. In step S55, the frequency of the new card is displayed, and the process returns to step S38. Then, the conversation with the other party is continued.

In step S51, if a new card has not been inserted within a predetermined time, the determination in step S56 becomes affirmative, and the process ends through steps S34 and S35. If it is determined in step S53 that the card is an abnormal card, the same processing as in steps S7, S8, and S11 is performed. However, the display in this case is performed in Japanese instead of English.

As described above, in the present embodiment, when the remaining call time of the card during the call falls below the reference, a message to that effect is displayed, and the user instructs to change to a new card. Then, if the user changes to a new card, the call is continued and the information in the card recorded on the previous card can be automatically recorded on the new card. Therefore, convenience for the user is good.
