SIM-KARTE FÜR MOBILTELEFON UND ENTSPRECHENDES MOBILTELEFON, VERFAHREN UND PROGRAMMPRODUKT

摘要

The user identification card (200) comprises a first file (201) including an HPLMN identifier, a second file (202) in which a current mobile telephony network the subscriber is connected to is defined, and a third file (203) in which at least one preferred mobile telephony network is defined by means of at least one identifier. When a predetermined event (A) occurs, it is verified whether the mobile phone is connected to a preferred network defined in the third file or to its HPLMN, and if it is not, a current network identifier is modified in the second file so that it has the value of a preferred network identifier selected from the third file (203), and a command for reconnecting the mobile phone to a mobile telephony network is sent to the mobile phone terminal (100).
