Abstract: Provided is a method for downloading a profile from a SM-DP+, Subscription Manager-Data Preparation Plus, to a secure element of a device, wherein the SM-DP+ stores profiles classified in three categories: a Preferred profile type; an Authorized profile type; and a Forbidden profile type, a profile type that has been downloaded on a device with failure. The method comprises includes retrieving by the SM-DP+ a device type identifier of the device and selecting in the categories a profile of either a Preferred profile type or an Authorized profile type, based on the device type identifier, a profile of the Preferred profile type having, for the selection, a higher priority than a profile of the Authorized profile; and downloading from the SM-DP+ to the device the selected profile and installing it in the secure element.

Abstract: Provided is a method for informing a mobile network operator server which profile of a profile type should be downloaded from a SM-DP+, Subscription Manager—Data Preparation, to a secure element comprised in a device, the SM-DP+ storing profiles classified in three categories: Preferred profile type, Authorized profile type and Forbidden profile type. The method includes method generating, by the mobile network operator server or the SM-DP+ an Eligibility ID, and sharing the Eligibility ID between the mobile network operator server, the SM-DP+ and the device for pairing the messages exchanged between them; transmitting from the device to the SM-DP+ information on the secure element and the device; and transmitting from the SM-DP+ to the mobile network operator server the information on the profile type to be downloaded in the secure element, based on the information on the secure element and the device. Other embodiments are disclosed.

Abstract: A method for establishing OTA sessions between terminals and an OTA server in a telecommunications network, each of the terminals interacting with a security element capable of interrogating the OTA server to establish a secure session in order to download data from the OTA server via a reverse proxy server in order to update security elements. The method includes provision by an OTA server to reverse proxy server of a list of identifiers of security elements for which an update is available; only establishing a secure session between the security elements and the OTA server for the security elements having identifiers included in said list.
