Abstract: A wireless communication terminal has a function of performing data communication with a server connected to a network, and includes a communication controller which selects a predetermined port number from among a plurality of port numbers allocated for data communication with the server, and using this communication port number to perform data communication with the server, and a storage unit which stores the communication port number; while performing a process to establish a communication connection with the server, if the communication controller receives information indicating that communication connection is impossible from the server, it selects a port number which is different from the communication port number stored in the storage unit as a new communication port number, and performs the process again.
