PROXIMITY-BASED SIM CARD SUBSCRIBER AUTHENTICATION

Abstract: examples of the present disclosure describe systems and methods for preventing unauthorized subscriber identity module (sim) card swapping by implementing proximity-based sim card subscriber authentication. in examples, when a communications service provider receives a request to move a subscriber phone number to a new sim card, the new sim card is activated in a locked state. in the locked state, certain features (e.g., receiving calls and text messages/texts) are disabled until the subscriber's identity is confirmed using proximity-based authentication. in examples, proximity-based sim card subscriber authentication is performed using a token provided by a physical authentication device within proximity to a subscriber mobile device including the new sim card. upon successful proximity-based sim card subscriber authentication, the new sim card is activated in an unlocked state.
