A portable information terminal is disclosed which can prevent a large amount of money from being imposed on a user while the user does not recognize it and wherein an original state of net surfing can be restored readily even if packet communication is disconnected. If a packet communication data integrated amount within an accounting unit period exceeds a maximum value for a packet communication data integrated amount within which the charge is fixed within the accounting unit period, a control section controls a display section to display "excess" and performs a process of an operation set arbitrarily by a user such as, for example, 'disconnect', 'saving' or 'alarm'. This can be prevent a large amount of charge from being imposed on a user while the user does not recognize it. If 'saving' is performed, where the portable information terminal has a browser incorporated therein, automatic image reading of a browser is turned off to save the packet communication data amount.
