A portable radio information terminal is capable of operating at a plurality of phases to execute functions different from each other. The portable radio information terminal has a transition-request-input detecting means for detecting an input signal generated by an input device in the course of an operation carried out at any current phase of the same plurality of phases to request an inter-phase transition, an inter-phase transition means for suspending the operation carried out at the current phase and for executing a transition from the current phase to another phase determined by a result of detection output by the transition-request-input detecting means and a phase-processing executing means for at least calling and displaying a screen of the other phase to which an inter-phase transition has been executed by the inter-phase transition means. As a result, it is possible to provide a portable radio information terminal that allows a phase transition to occur therein as a result of a simple operation to specify an input and is capable of displaying a screen, and to provide a screen displaying method suitable for the portable radio information terminal.
