When acquiring a PRL, a mobile phone judges whether the newly acquired PRL contains a base station satisfying a selection condition specifying (i) a communication mode, (ii) whether a base station available via a roaming service is selectable, and (iii) a data communication mode. On judging that such a base station is contained, the mobile phone retains the current selection condition. On judging, on the other hand, that such a base station is not contained, the mobile phone changes the selection conditions so that all the base stations contained in the PRL are made selectable for communication.
