A wireless communication device includes a battery voltage monitoring section, which monitors the amount of decline in output voltage when a network connection section is connected to a wireless communication network to which the wireless communication device should be connected based on a communication, request; and an operation control section, which selects fewer wireless communication networks than the wireless communication device should be connected to based on the communication request if a predicted voltage calculated by subtracting the amount of decline from the output voltage is less than or equal to a predetermined threshold, and connects the network connection section to the selected one or more wireless communication networks. Based on the amount of decline, the operation control section selects one or more wireless communication networks so that the predicted voltage exceeds the predetermined threshold.
