  The wireless communication subsystem 130 is periodically activated to automatically scan in the frequency band in which the presence or absence of radio waves transmitted from the wireless LAN access point can be used around the current position (S21). When the radio wave is received (S22: YES), a connection information request such as SSID is transmitted from the mobile phone 100 to the access point (S23). The connection setting information and the security function are acquired from the access point (S24), and it is checked against the data stored in the memory 160 whether or not the received radio wave is a user's subscribed wireless LAN service (S25). If the collation matches and the service network is connectable by the user (S26: YES), the type of wireless LAN service and various types of wireless LAN information are stored in the memory 160 (S27).
