A loading package is adapted for loading a profile for a subscription into a subscriber identity module. A loading sequence through the implementation of which in the subscriber identity module the profile is set up in the subscriber identity module. A profile loading counter sequence is generated on the basis of a counter reading of a profile loading counter maintained at a data preparation server; is adapted to load into the subscriber identity module a profile loading counter with the generated counter reading; and is loaded into the subscriber identity module before the loading sequence. The profile loading counter sequence is further adapted if no implemented profile loading counter is present in the subscriber identity module, to implement the profile-loading counter in the subscriber identity module with a counter reading which determines an admissible number of times which the loading package may be loaded into the subscriber identity module.
