Defense Secure Mobile Phones Act of 2025

HR 6558, the Defense Secure Mobile Phones Act of 2025, requires the Department of Defense (DoD) to provide wireless mobile phones with enhanced cybersecurity protections to senior officials and employees performing sensitive national security functions. The law mandates that all such phones and related telecom services must include encryption for data on devices and communications, capabilities to prevent tracking by rotating device identifiers, and continuous device monitoring. DoD must report to Congress within 180 days detailing the contracts used, criteria for identifying affected personnel, and associated costs. This bill directly affects DoD personnel handling sensitive security work by implementing specific technical security standards for their mobile devices.
