A method for configuring a communication device, whereby specific adaptions of the communication device are performed, characterized by the following steps: - A communication link is established from the communication device to an external auto-configuration-server; - Identification data, which are related to the communication device, are transmitted from the communication device to the external auto-configuration-server for the purpose of authentication of the communication device, whereby chip card related identification features are transmitted as identification data, whereby the chip card related identification features are assigned to a chip card for the identification thereof, whereby the chip card is assigned to the communication device, whereby the chip card is provided as a SIM-card, whereby an International Mobile Subscriber Identification is assigned to the chip card as a chip card related identification feature, whereby a chip card related PIN, in particular a super PIN, is assigned to the chip card as a chip card related identification feature, and whereby the International Mobile Subscriber Identification and the chip card related PIN are transmitted from the communication device to the external auto-configuration-server as identification data in form of two different chip card related identification features, - The transmitted identification data are authenticated in the external auto-configuration-server, while for the authentication the transmitted identification data are compared by the auto-configuration-server with identification data being stored in the auto-configuration-server, while it is checked in the auto-configuration-server, to which extent the transmitted identification data match with the stored identification data, whereby the stored identification data are linked to configuration data, which are stored in the auto-configuration-server; - Upon a successful authentication a configuration of the communication device is performed in such a way, that upon a match of the transmitted identification data with the stored identification data the configuration data being linked to the stored identification data are automatically transmitted from the auto-configuration-server to the communication device, are received there and are configured on the communication device. - A communication link is established from the communication device to an external auto-configuration-server; - Identification data, which are related to the communication device, are transmitted from the communication device to the external auto-configuration-server for the purpose of authentication of the communication device, whereby chip card related identification features are transmitted as identification data, whereby the chip card related identification features are assigned to a chip card for the identification thereof, whereby the chip card is assigned to the communication device, whereby the chip card is provided as a SIM-card, whereby an International Mobile Subscriber Identification is assigned to the chip card as a chip card related identification feature, whereby a chip card related PIN, in particular a super PIN, is assigned to the chip card as a chip card related identification feature, and whereby the International Mobile Subscriber Identification and the chip card related PIN are transmitted from the communication device to the external auto-configuration-server as identification data in form of two different chip card related identification features, - The transmitted identification data are authenticated in the external auto-configuration-server, while for the authentication the transmitted identification data are compared by the auto-configuration-server with identification data being stored in the auto-configuration-server, while it is checked in the auto-configuration-server, to which extent the transmitted identification data match with the stored identification data, whereby the stored identification data are linked to configuration data, which are stored in the auto-configuration-server; - Upon a successful authentication a configuration of the communication device is performed in such a way, that upon a match of the transmitted identification data with the stored identification data the configuration data being linked to the stored identification data are automatically transmitted from the auto-configuration-server to the communication device, are received there and are configured on the communication device.
