<p>According to the invention, the unblocking of a mobile telephone card (1) which is blocked by means of an access code (10) is carried out by the user making contact (SI) with a service device (20; 30), authenticating (S2) the user in relation to the service device (20; 30) and automatically unblocking the mobile telephone card (1) by means of the service device (20; 30). As a result, the service device can be operated by a card issuer and/ or a mobile telephone network operator or in a third party which is independent and is trustworthy. The contact of the user with the service device (20; 30) can take place either by telephone via a blocking module (8) of the mobile telephone (12) or by personally locating the service device (20; 30). Personal data (16, 16') is compared to reference data (21, 31) which is present in the service device (20, 30) during authentication (S2). A new access code (10') is established on the mobile telephone card (1) directly through the service device (20, 30) or indirectly through the central point (20', 20 ) via an interface (15, 25, 35) of a mobile telephone or the service device (20, 30) in order to unblock said mobile telephone card (1).</p> |
