A method for automatically forwarding messages according to a SMS and/or MMS format in mobile radio networks, which messages are directed to a message receiver registered with a contacting information item as subscriber in a mobile radio network and addressed to the contacting information item, wherein a) the message receiver stores an addressing information item for receiving the messages by means of a computer device of the mobile radio network, which device is adapted to administrate the forwarding; b) the computer device of the mobile radio network links the contacting information item to the stored addressing information item; c) the computer device of the mobile radio network receives a message intended for the message receiver under the contacting information item; d) the computer device of the mobile radio network replaces the contacting information item of the received message with the addressing information item or complements the contacting information item with the addressing information item; characterized in that e) in case of a stored forwarding respectively redirecting of voice calls, the storage of an addressing information item by means of the computer device of the mobile radio network, which device is adapted to administrate the forwarding, will be realized automatically by an information item with respect to the addressing information item for the forwarding respectively redirecting of messages from the Home Location Register; or the storage of an addressing information item for the forwarding of messages by the message receiver will be realized by means of a user interface provided by a web application and if the addressing information item is stored, an information item with respect to the addressing information item for the forwarding respectively redirecting of voice calls will be automatically sent by the computer device of the mobile radio network, which device is adapted for forwarding messages, to the Home Location Register; f) the message receiver configures, via the user interface provided by the web application, whether a copy of the messages shall be sent to a message receiver's terminal which uses the contacting information item; g) if the message receiver configured that a copy of the messages shall be sent to the contacting information item, a copy of the message will be sent to the message receiver's terminal which uses the contacting information item; h) the message received by the computer device of the mobile radio network will be transmitted to at least one other computer device which converts the message into a format corresponding to the type of the addressing information item, wherein a direct forwarding can be established; and i) the thus treated message will be sent by the other computer device to the addressing information item. a) the message receiver stores an addressing information item for receiving the messages by means of a computer device of the mobile radio network, which device is adapted to administrate the forwarding; b) the computer device of the mobile radio network links the contacting information item to the stored addressing information item; c) the computer device of the mobile radio network receives a message intended for the message receiver under the contacting information item;
