Abstract
A surveillance method for a mobile telecommunications terminal having an eSIM card. A plurality of subscription profiles are stored in the eSIM card. The surveillance method includes steps of incrementing a counter each time a change of subscription profile order is received, determining a number of change of subscription profile orders received during a predetermined duration, and, if the number of change of subscription profile orders received during the predetermined duration is greater than a predetermined threshold, deducing therefrom that operation is suspect.
