The device also has a security module app that receives a cellular broadcast message and extracts logical IDs therefrom. This processes a targeted cellular broadcast message embedded in the payload of the cellular broadcast message, based on whether a logical ID, also embedded in the payload, of the targeted cellular broadcast message is on the inclusion list. It then formats it for consumption by an electronic user device app that receives data via a data channel when available. ## Claims ### Claim 1 An electronic user device comprising: inclusion list storage, comprising electronically readable memory, for storing an inclusion list, the inclusion list indicating included logical IDs;
