摘要

A method for transmitting parameter data between a telecommunications network and a telecommunications terminal and for activating and/or changing and/or deactivating a communication profile on the telecommunications terminal, which communication profile is defined by the parameter data, wherein the telecommunications terminal has an eUICC module, wherein the eUICC module provides the functions of an embedded universal integrated circuit card (eUICC), wherein the eUICC module is used to store the parameter data for using the telecommunications network in accordance with the communication profile in a memory area associated with the eUICC module, wherein the communication profile is associated both with a network operator of the telecommunications network and with the telecommunications terminal or with a user of the telecommunications terminal, wherein the parameter data are transmitted to the telecommunications terminal and the communication profile is activated and/or changed and/or deactivated in the eUICC module of the telecommunications terminal by performing the following steps: in a first step, the parameter data are transmitted from the telecommunications network to the telecommunications terminal, wherein the profile data have an associated piece of MIME type information (multipurpose Internet mail extensions type information), in a second step, which follows the first step, a MIME handler application of the telecommunications terminal is activated – based on the MIME type information – such that the parameter data are used to activate/or change and/or deactivate the communication profile in the telecommunications terminal by virtue of the MIME handler application having at least partial access to the eUICC module and bringing about a change and/or addition to the content of the memory area associated with the eUICC module.
