Method for obtaining a command relating to a network access profile of an "embedded universal integrated circuit card", eUICC, security module, said security module being incorporated in a communication equipment and being associated with a physical identifier, EID, the method comprising the following steps: • (a) obtaining, by way of a communication terminal, the physical identifier EID of said security module, and computing (E1-E4) an anonymous identifier, TEID, of the security module from the physical identifier EID and a randomly obtained parameter, Pa, called random parameter; • (b) transmitting (E5, E6) a command obtainment request, by way of said terminal, via a first server, called "operator server", to a second server, called "data preparation server", said obtainment request including the anonymous identifier TEID of the security module; followed by preparing the command by way of the data preparation server and storing the command associated with the anonymous identifier TEID; and followed by sending, to a server, called "discovery server", a prepared command information notification associated with the anonymous identifier TEID, the discovery server consequently storing the address of the command preparation server, associated with the notification; • (c) obtaining, by way of the communication equipment, the random parameter (Pa) and computing the anonymous identifier TEID from the physical identifier EID of the security module and the random parameter Pa; • (d) sending, by way of the communication equipment, to the third server, called "discovery server", an information obtainment request intended to obtain the command, said information obtainment request comprising the anonymous identifier TEID, in order to obtain, in response, from the discovery server, an address of the preparation server. • (a) obtaining, by way of a communication terminal, the physical identifier EID of said security module, and computing (E1-E4) an anonymous identifier, TEID, of the security module from the physical identifier EID and a randomly obtained parameter, Pa, called random parameter; • (b) transmitting (E5, E6) a command obtainment request, by way of said terminal, via a first server, called "operator server", to a second server, called "data preparation server", said obtainment request including the anonymous identifier TEID of the security module; followed by preparing the command by way of the data preparation server and storing the command associated with the anonymous identifier TEID; and followed by sending, to a server, called "discovery server", a prepared command information notification associated with the anonymous identifier TEID, the discovery server consequently storing the address of the command preparation server, associated with the notification; • (c) obtaining, by way of the communication equipment, the random parameter (Pa) and computing the anonymous identifier TEID from the physical identifier EID of the security module and the random parameter Pa; • (d) sending, by way of the communication equipment, to the third server, called "discovery server", an information obtainment request intended to obtain the command, said information obtainment request comprising the anonymous identifier TEID, in order to obtain, in response, from the discovery server, an address of the preparation server.
