A method for the at least partially automatic configuration of a mobile terminal that is operable with a mobile subscriber identification module, SIM, in a mobile radio network, in particular according to a GSM, GPRS, UMTS and/or LTE radio network standard, after the preferably first registration of the mobile terminal with the mobile subscriber identification module, SIM, in the mobile radio network, comprising the following steps carried out by the mobile radio network: a) receiving a short message in a reception module, SMSC, of a configuration device of the mobile radio network, wherein the short message contains data which identify the mobile subscriber identification module, SIM, and data which identify the mobile terminal; b) transmitting the received short message from the reception module, SMSC, to a first test module of the configuration device and to a second test module (7, 8) of the configuration device; c) determining mobile network operator specific data for the mobile subscriber identification module, SIM, by means of the first test module on the base of the data which identify the mobile subscriber identification module, SIM; d) generating a first configuration data set by the first test module, wherein the configuration data set contains mobile network operator specific data for the mobile subscriber identification module, SIM; e) determining terminal specific data for the mobile terminal by the second test module (7, 8) on the base of the data which identify the mobile terminal; f) generating a second configuration data set by the second test module (7, 8), wherein the configuration data set contains terminal specific data for the mobile terminal; and g) sending the first configuration data set and the second configuration data set from the configuration device to the mobile terminal; characterized in that the second configuration data set will be sent to the mobile terminal via a communication connection, session, established as ip connection between the second test module and the mobile terminal, wherein the second test module will send a short message to the mobile terminal, which short message is not visible for the user of the mobile terminal, for establishing the communication connection configured as ip connection, wherein the short message contains data for establishing the communication connection, session, configured as ip connection, comprising addressing data for addressing a database which manages terminal specific data about functions, applications and/or services supported by mobile terminals and/or authentication data for authenticating the mobile terminal with respect to the database which manages terminal specific data about functions, applications and/or services supported by mobile terminals, if the communication connection, session, configured as ip connection is established, the second test module (7, 8) will read information about functions, applications and/or services supported by the mobile terminal out of the mobile terminal, on the base of this information the module will query the terminal specific data about functions, applications and/or services supported by the mobile terminal from the database and will generate the second configuration data set on the base of the queried data, and an application carried out on the mobile subscriber identification module, SIM, is configured and/or adapted to determine whether the actual combination or mating of the mobile terminal used with the mobile subscriber identification module, SIM, has already been used at a former time. a) receiving a short message in a reception module, SMSC, of a configuration device of the mobile radio network, wherein the short message contains data which identify the mobile subscriber identification module, SIM, and data which identify the mobile terminal; b) transmitting the received short message from the reception module, SMSC, to a first test module of the configuration device and to a second test module (7, 8) of the configuration device; c) determining mobile network operator specific data for the mobile subscriber identification module, SIM, by means of the first test module on the base of the data which identify the mobile subscriber identification module, SIM; d) generating a first configuration data set by the first test module, wherein the configuration data set contains mobile network operator specific data for the mobile subscriber identification module, SIM; e) determining terminal specific data for the mobile terminal by the second test module (7, 8) on the base of the data which identify the mobile terminal; f) generating a second configuration data set by the second test module (7, 8), wherein the configuration data set contains terminal specific data for the mobile terminal; and g) sending the first configuration data set and the second configuration data set from the configuration device to the mobile terminal;
