PROBLEM TO BE SOLVED: To achieve a portable wireless terminal which can prevent error in proper use of a plurality of its own telephone numbers. SOLUTION: A call termination record in which the partner telephone number is made to correspond with its own termination telephone number is registered at a termination call record storage 14b. When a call is originated, a decision is made whether the source partner telephone number is a partner telephone number terminated before or not with reference to the termination call record. If it is a partner telephone number terminated before, its own telephone number used at that time is extracted from the termination call record and a call is originated, thus error can be prevented in proper use of a plurality of its own telephone numbers. As a result, such an evil can be eliminated as some of a plurality of its own telephone numbers excepting those already known to the partner are known to the partner or the communication partner is confused by termination of call from an unknown telephone number.
