A user equipment for wireless communication, configured to operate in a cellular network, includes a credential container. The user equipment sends a set of payload items to a central server communicatively coupled to the cellular network, wherein the user equipment is configured to send an attach request message to the cellular network comprising a preconfigured qualifier for at least one of the user equipment and the credential container. The user equipment is further configured—to retrieve an authentication request message from the cellular network comprising a random value and an authentication code, —to determine a response token comprising a preconfigured identifier stored in at least one of the user equipment and the credential container and at least one out of the set of payload items, and—to submit said response token with an authentication failure message to the cellular network for forwarding to the central server.
