This bill directs the Comptroller General, the federal government's chief auditor, to investigate and report on the Federal Communications Commission's Mandatory Disaster Response Initiative, which requires wireless providers to maintain communications coverage during emergencies and disasters. The report, due within 180 days of the bill's enactment, must evaluate how well the initiative works overall and specifically assess its performance during California's January 2025 wildfires. The investigation will also identify any gaps in cellular coverage, roaming arrangements between providers, or coordination problems under the program, and provide recommendations for improvements. The bill essentially seeks accountability for how well telecommunications companies are meeting their obligations to keep people connected when disasters strike.
