PROBLEM TO BE SOLVED: To provide a wireless mobile terminal that allows a user to recognize whether or not a stable speech is available. SOLUTION: The wireless mobile terminal consists of a wireless section 1 that uses a radio wave to transmit/receive a wireless signal, an out-of-zone judging section 2 that judges whether or not a mobile terminal is resident outside the zone on the basis of the strength of a radio wave received by the wireless section 1, an identification code storage section 3 that stores an identification code of a wireless base station in a waiting state, an out-of-zone history storage section 4 that stores the identification code stored in the identification code storage section 3 when the judging section 2 judges that the mobile terminal is resident outside the zone, a history judging section 5 that judges whether or not a wireless base station in a waiting state has a history by comparing the identification code stored in the identification code storage section 3 with contents of the history storage section 4, and a display section 6 that displays it when the out-zone judging section 2 judges that the mobile terminal stays within a zone and the history judging section 5 judges that the wireless base station in a waiting state has the out-of-zone history. |
