1. A method for recovering a profile of a MNO downloaded in a first secure element integrated in a first terminal, wherein said first terminal is unavailable and/or not operational, at the level of a second secure element integrated in a second terminal, said method comprising:
Transmitting from said first terminal to a SM-DP+ a first secured message containing a personal code known by the user of said first terminal along with a unique identifier of said profile, before said first terminal has become unavailable and/or not operational, wherein said personal code and said unique identifier correspond to a backup of said profile, wherein said backup of said profile is identical to said profile;
After having tested that said first secure element is not operational anymore, sending from said MNO to said SM-DP+ a recover code known by said user and said unique identifier of said profile;
Sending from said second terminal to said SM-DP+ a second secured message containing said recover code, said personal code and a unique identifier of said second secure element;
Comparing at said SM-DP+ said first and second secured messages and if they correspond, transmitting to said second terminal said backup of said profile, installing in said second secure element said backup of said profile and, upon installation success, notifying said MNO that said backup of said profile has been installed in said second secure element.
