Abstract
A data communication terminal carries out data communication via a first communication network in which accounting is made according to a transmitted/received data amount, and via a second communication network in which accounting is made according to a connection time. The terminal calculates a communication charge according to the transmitted/received data amount of the data communication carried out via the first communication network, and according to the connection time of the data communication carried out via the second communication network. The terminal sets a communication charge limit amount for a set of objective data to be transmitted/received, selects one of the first and second communication networks to carry out data communication, calculates the communication charge for the data communication carried out by the selected one of the first and second communication networks, and judges whether the calculated charge has reached the communication charge limit amount to warn a user.
