PROBLEM TO BE SOLVED: To allow a radio communication module for processing an audio signal by an analog method and radio communication module for processing the audio signal by a digital method to be replaced with a common use mobile jacket for use. SOLUTION: A radio communication terminal device is so configured that a container, i.e., a W-SIM1 system for processing the audio signal by a digital signal and container, i.e., a C-SIM2 system for processing the same by an analog signal are inserted into a slot 9 of the common use mobile jacket 7. When the W-SIM1 is inserted into the mobile jacket 7, a route switch 20 is switched to the W-SIM1, and a jacket control portion 16 is disconnected from an amplifying portion 21 and USIM 22 and then connected to a codec portion 17, so that audio communication is carried out by the digital method. When the C-SIM2 is inserted into the mobile jacket 7, a route switch 20 is switched to the C-SIM2, and a jacket control portion 16 is connected to the amplifying portion 21 and USIM 22 and disconnected from the codec portion 17, thereby enabling audio communication by the analog method.
