A dual-mode telecommunication device and its driving method are disclosed. The dual-mode telecommunication device electrically connects with a voice input/output communication unit for transmitting/receiving an analog voice signal. In addition, the dual-mode telecommunication device comprises a processor and a switch, wherein the processor is used for detecting/transforming the signal type and generating a control signal based on a detection result. The switch is used for assisting the voice input/output communication unit performing an Internet telecommunication mode or a PSTN (Public Switched Telephone Network) telecommunication mode, alternatively based on the control signal. The driving method is used for determining whether assisting the voice input/output communication unit to electrically connect with the Internet or not by the switch based on detecting a signal which contains an IP, a status result and a dial-tone result of the voice input/output communication unit.
