For loading or reloading chipcards, used in mobile radio devices (10), or user accounts assigned to the chipcards with a credit for a monetary amount value, a service number of a central unit (30) is called using a communications device, by means of the communications device at least a value code (13) of a prepaid value card (11) and an identification of the chipcard or the user account to be loaded or reloaded is transmitted, and a reloading unit transmits the credit to the chipcard or to the user account assigned to the chipcard and stored on a central customer database, whereas the chipcard is assigned to a call number of a user of the mobile radio network (50), whereby the central unit (30) determines, by means of a database, a first reloading unit (41) of a first mobile radio network operator, the issuer of the prepaid value card (11), the central unit (30) transmits, via a first communications channel (50/51), the value code (13) and a proxy MSISDN to the first reloading unit (41), and the first reloading unit (41) credits a monetary amount value, which is assigned to the value code (13), to the central unit (30) by means of the proxy MSISDN, and the central unit (30) transmits, via a second communications channel (50/52), the monetary amount value and the identification of the chipcard or the user account to be loaded or reloaded to a second reloading unit (40) of a second mobile radio network operator, with whom the chipcard is approved for use of the mobile radio network (50) for loading or reloading the chipcard. Used as identification of the chipcard or the user account can be a MSISDN (Mobile Subscriber ISDN) assigned to the chipcard, i.e. the call number, and/or an IMSI (International Mobile Subscriber Identification). The chipcards can be, e.g. SIM (Subscriber Identification Module) cards or smart cards. An advantage of the invention is, inter alia, that no special contractual agreements between the individual mobile radio network operators are necessary for mutual recognition of value cards (11) with value codes (13) from different mobile radio network operators. On the contrary, a single contractual agreement with a central unit (30) according to the invention or the operator thereof suffices for a mobile radio network operator.
