<p>The invention relates to a method, an apparatus and an arrangement for calculating the value of an amount in a first currency in terms of a desired second currency. The method comprises the steps of entering the value of an amount in a first currency in control means of a receiver (1). A scaling factor is retrieved from memory means of said receiver, said scaling factor describing a conversion between at least two different PLMN units. Said amount of said first currency is then converted to the equivalent amount of said second currency by said control means adapted to use said scaling factor for the conversion. Finally, the user is informed of the conversion result by means of a user interface (3) of the receiver (1). The apparatus performing the inventive method is included in a mobile station (1) and the arrangement is included in a public land mobile network, PLMN.</p> |
