A wireless communication terminal has a first wireless communication unit which performs data communication via a first wireless communication system and a second wireless communication unit which performs voice communication via a second wireless communication system. When an instruction of starting a voice communication is given, a temporal withdrawal process is started to the first wireless communication system, and an acquiring process of the second wireless communication system is started. After the voice communication ends, until a predetermined time elapses, an acquiring state of the second wireless communication system by the second wireless communication unit is continued. After the predetermined time has elapsed, the acquiring state of the second wireless communication system is cancelled, and a temporal withdrawal cancelling process is started to the first wireless communication system.
