Methods and device for personalizing a secure element (e.g., a eUICC) may include or implement operations for receiving a personalization request issued by an operator to download a personalized profile in compliance with a model into the secure element, and the request may include personalization data, an identifier of the secure element and the identifier of the model. Other operations may include using the identifier of the secure element to identify a pre-personalization server suitable for pre-personalizing the secure element; obtaining a message from the pre-personalization server, the message including a pre-personalization script for the secure element based on the description of the model; generating a personalization script for the secure element by using the pre-personalization script and the personalization data; and sending the personalization script to the secure element, the secure element being suitable for executing the personalization script to install the personalized profile in the secure element.
