"The process to achieve the calculation of the value of an amount in a first currency in terms of a second currency desired mobile station, and,The provision in public terrestrial mobile networks.The invention relates to a process and a device and a provision for the calculation of the value of an amount of money in a first currency in terms of a second currency desired.The process comprises the steps of recording the value of an amount in a first currency n control device of a receiver (1).A scaling factor is retrieved from the memory device of said receiver, the ITL scaling factor describing a conversion between the at least two units PLMN different.The quantity of said first currency is then converted into equivalent amount of said second currency by said control device adapted for use with the factor of.Scalonamento for conversions. Finally, the user is informed of the result of the conversion through a user interface (3) to the receiver (1).The inventive device that performs the process is included in a mobile station (1) and the arrangement is included in a public land mobile network, PLMN.
