    Abstract: A mobile device, having a smart card within the mobile device, stores a Mobile Network Operator (MNO) profile for the mobile device in the smart card, where the MNO profile includes one or more network access credentials for accessing a wireless mobile network. The mobile device receives a customer request to delete the MNO profile, and sends, from the mobile device to a network node in the wireless mobile network, a request for profile deletion. The mobile device receives, responsive to the request from the network node, a deletion code; extracts, from the received deletion code, a deletion code signature and a public key of the network node. The mobile device validates the deletion code signature and the public key, and deletes, upon successful validation of the deletion code signature and the public key, the MNO profile from the smart card.

    Abstract: A device may scan for a carrier that includes an embedded Universal Integrated Circuit Card (eUICC), wherein the carrier is associated with a Mobile Network Operator (MNO). The device may hop on the carrier, authenticate with a network of the MNO without using an MNO profile stored in the eUICC, and gain limited access to the network in response to the authentication. The device may also register with the network while attached to the network. The registering may include downloading an operational MNO profile to the eUICC in the device and storing the MNO profile on the eUICC.

    Abstract: A mobile device sends a network attach request to a network node, and receives an authentication challenge from the network node, where the authentication challenge includes an authentication token, a random number, and a time variable associated with a current time at the network node. A microprocessor smart card of the mobile device retrieves the time variable from the authentication challenge, and starts a clock counter based on the retrieved time variable. The microprocessor smart card uses a current time represented by the clock counter to perform time expiration validation tests on certificates during Public Key Infrastructure (PKI) authentication or on authentication tokens during token-based authentication.
