A method for determining identification information on a user of a user terminal comprising a subscription of a second network, wherein the user terminal is requesting access to a first network, the method comprising - receiving, in a server, an access request message from an entity controlling at least partly the access to the first network, wherein the access request message is generated in response to a receipt of a data request access from an application residing in a memory of the user terminal, - determining, from the access request message, information relating to the subscription, - composing and delivering an identification request message from the server to the user terminal, the destination address of the user terminal is determined at least partly on the basis of the information relating to the subscription, and wherein the identification request message is configured to initiate an access request to a subscriber identity module in the user terminal causing to prompt the user to input an access code and to retrieve stored data from a secure element of the subscriber identity module in order to compare the input data to the stored data in the secure element, - receiving, from the user terminal, an indication of a successful identification of the user of the user terminal through an interaction of the user and the user terminal in response to the comparison indicating a match between the input access code by the user and the stored data retrieved from the secure element of the subscriber identity module, - retrieving, in response to the receipt of the indication, a pre-agreed at least one piece of information on the user of the user terminal from a location accessible to the server, and - composing and delivering the pre-agreed at least one piece of information on the user of the user terminal to the entity controlling at least partly the access to the first network. - receiving, in a server, an access request message from an entity controlling at least partly the access to the first network, wherein the access request message is generated in response to a receipt of a data request access from an application residing in a memory of the user terminal, - determining, from the access request message, information relating to the subscription, - composing and delivering an identification request message from the server to the user terminal, the destination address of the user terminal is determined at least partly on the basis of the information relating to the subscription, and wherein the identification request message is configured to initiate an access request to a subscriber identity module in the user terminal causing to prompt the user to input an access code and to retrieve stored data from a secure element of the subscriber identity module in order to compare the input data to the stored data in the secure element, - receiving, from the user terminal, an indication of a successful identification of the user of the user terminal through an interaction of the user and the user terminal in response to the comparison indicating a match between the input access code by the user and the stored data retrieved from the secure element of the subscriber identity module, - retrieving, in response to the receipt of the indication, a pre-agreed at least one piece of information on the user of the user terminal from a location accessible to the server, and - composing and delivering the pre-agreed at least one piece of information on the user of the user terminal to the entity controlling at least partly the access to the first network.
