As shown in FIG. 2, the handheld communication device 200 of the present embodiment includes a system processing unit 210, a CDMA communication processing unit 220, a GSM communication processing unit 230, a CDMA chip card holder 240, and a GSM chip card holder 250. The switching unit 260 is further disposed between the CDMA communication processing unit 220 and the CDMA chip card holder 240; and the switching unit 270 is disposed between the GSM communication processing unit 230 and the GSM chip card holder 250. The following is a detailed description of the functions of the various components in the handheld communication device 200: the CDMA chip cartridge 240, hence the name, is used to configure the CDMA chip. Similarly, the GSM chip cartridge 250 is used to configure a GSM chip. However, as described above, since the structure and the working principle of the CDMA chip card holder 240 and the GSM chip card holder 250 are the same, in this embodiment, the type of the wafer card disposed thereon is not limited, and the user can select the configuration as needed. For wafer cards of the same or different types (including GSM, PHS, and CDMA), the wafer card disposed in the CDMA wafer deck 240 will be referred to as a first wafer card, and the wafer card disposed in the GSM wafer card holder 250 will be referred to as a first Two wafer cards to show the difference.

The CDMA communication processing unit 220 is connected to the CDMA chip card holder 240 through the switching unit 260 to access the data of the first chip card.
