When active software makes a request for measuring position information, during roaming, a control unit does not execute GPS measurement, but notifies the software of an error indicating that, for example, measurement is failed, and thereby prevents establishment of communication for a function which cannot be executed by the software.

Mobile radio terminal

A mobile terminal determines, if a communication request is input, whether a connection destination mobile communication network system is a first mobile communication network system as a subscription mobile communication network system, or a second mobile communication network system as a roaming destination mobile communication network system. When it is determined that the connection destination mobile communication network system is the second mobile communication network system, a mobile terminal user is notified of information indicating a roaming state. When an input of a connection destination change request is received, a mobile communication network system reselection process is performed for changing the connection determination mobile communication network system from the second mobile communication network system to the first mobile communication network system.
