Abstract

L'invention concerne un procédé d'initialisation d'une carte universelle à circuit intégré (UICC) permettant d'obtenir des services de réseau sur un dispositif sans fil, ce procédé consistant à tenter de lire des fichiers système à partir de la carte universelle à circuit intégré. Le procédé consiste également à déterminer si la lecture des fichiers système à partir de la carte universelle à circuit intégré a échoué. Le procédé consiste en outre à tenter un nouvel essai de lecture des fichiers système lorsqu'il y a une défaillance de lecture des fichiers système.
