Abstract: The invention proposes several improvements related to the management of secure elements, like UICCs embedding Sim applications, these secure elements being installed, fixedly or not, in terminals, like for example mobile phones. In some cases, the terminals are constituted by machines that communicate with other machines for M2M (Machine to Machine) applications.

Abstract: The invention provides a method for activating the subscription of an UICC, said UICC comprising an activation application, said method comprising the step of activating the subscription of the holder of the UICC by sending a message to an activation server, said message being sent by the activation application to the activation server by using an IP based communication.

Abstract: The invention is a method of managing an application embedded in a secured electronic token. The token is intended to receive a message from a server machine. The message has a header and a body. The token comprises an agent able to manage the message. The method comprises the steps of: a) registering the application in the agent by associating a reference of the application with a value of an element of the message header, b) when the message is received from the server machine, forwarding part of the message to the application if the message header contains an element having the value associated to the reference of the application.

Abstract: Transmission of data between a download server and a communicating object through a communications network is initiated by a registration server, by transmitting connection parameters received from the download server to the communicating object via a first data channel opened by a first agent of the communicating object after attaching the object to the network. As a function of the connection parameters, a second agent in the communicating object opens a second data channel to the download server so as to transmit the data therein. As long as the first data channel is open, other servers can initiate a transmission via the registration server.
