Abstract
A method for detecting that a removable secure element has been temporarily disconnected from a first device includes: Providing by the secure element to the first device a first Temporal Global Identity; Entering the first device in the sleeping mode; If the secure element is inserted and used by a second device during the sleeping mode of the first device, replacing in the secure element the first Temporal Global Identity by a second Temporal Global Identity and providing the second Temporal Global Identity to the second device; When getting out from the sleeping mode by the first device, reading by the first device the Temporal Global Identity stored in the secure element; If the Temporal Global Identity read is not the same than the stored Temporal Global Identity, sending to an MNO server a message to indicate that the secure element has been used by another device.
