Abstract
A method of performing a switch from a first mobile network to a second mobile network by a mobile terminal comprising a secure element includes the steps of: (a) attaching to the first mobile network using a first attachment message containing a first identification data element, preferably a first IMSI, of a first subscription profile; and (b) attaching to the second mobile network by an attachment process including a second attachment message containing a second identification data element, preferably a second IMSI, of a second subscription profile. The second mobile network is configured to monitor at least parts of the attachment process, to determine the second identification data element contained therein and to forward this information to a subscription management server in order to confirm the successful attachment of the secure element to the second mobile network.
