The invention relates to methods and devices for locking a secure element (20), such as a subscriber identity module (SIM) or a universal integrated circuit card (eUICC/UICC), to a mobile terminal (14). According to the invention the order in which a mobile terminal, for instance, during the start-up sequence of the mobile terminal (14), accesses files (26a, 26b, 27a, 27b, 28a) stored on the secure element (20) is used as a kind of fingerprint of the mobile terminal (14). Preferably, the fingerprint is derived from the file access profile of the mobile terminal (14) by applying a hash function to the file access profile. If the fingerprint derived from the file access profile of the mobile terminal (14) differs from a nominal fingerprint, then it is concluded that the mobile terminal (14) is not the mobile terminal the secure element (20) has been locked to originally. Otherwise, i.e. if the fingerprint of the mobile terminal (14) is identical to the nominal fingerprint, it is concluded that the mobile terminal (14) is the mobile terminal the secure element (20) has been locked to originally.
