Wireless service providers with facilities in high fire-threat or high earthquake threat districts must maintain continuous capability to provide 911 access, 211 access, emergency alerts, and basic internet for emergency information during normal and emergency conditions

Providers must submit written network resiliency plans to the Public Utilities Commission by April 1, 2027, and at least every three years thereafter, with revised plans required within 90 days of material changes

Network resiliency plans must include backup energy systems capable of sustaining minimum service levels for at least 72 consecutive hours, with annual testing and documented fuel capacity or resupply contracts

Plans must address network redundancy with no single points of failure, physical hardening against wildfires and earthquakes, procedures for rapid service restoration, and deployment of temporary facilities like mobile cell sites

The PUC may impose fines, require corrective actions, or take other enforcement measures for noncompliance, and violations constitute crimes under state law
