T-Mobile US, Inc. worked with communities across America to prepare, it is strengthening emergency preparedness through continued investments in network resilience, intelligent technologies and expanded support for communities and first responders. In 2025 alone, T-Mobile US, Inc. supported communities and first responders through more than 60 disaster events nationwide and deployed thousands of assets to help maintain connectivity, including thousands of generator deployments and refueling missions. AI-powered network intelligence restoring connectivity faster, including tens of thousands of automated adjustments during Winter Storm Fern. T-Satellite with Starlink supported more than 250,000 users with over 1.5 million messages sent during Fern, and is now expanding to international locations with reciprocal roaming service in Canada and New Zealand. An expanding fleet of deployable assets, including smaller rapid-deploy SatCOLTs, hybrid generators and enhanced drone capabilities. Real-time telemetry tools helping teams respond faster, monitor network conditions remotely and keep sites running longer. T-Mobile US, Inc.’s nationwide 5G Advanced network is designed to perform under pressure and is supported by a robust fleet of rapidly deployable assets, including SatCOLTs (Satellite Cell on Light Trucks), SatCOWs (Satellite Cell on Wheels), COWs (Cell on Wheels), generators, portable satellite antennas and drones. These assets are actively used to quickly restore and maintain connectivity when extreme weather and other emergencies impact network performance, supporting first responders, public safety partners and the communities they serve in critical moments. The company continues to expand its fleet and capabilities with additional assets, including: Sleep units that support extended field operations and help crews stay on site, supporting impacted communities for longer periods of time; New drones with enhanced capabilities that provide real-time situational awareness, helping teams assess conditions from above and make faster, more informed decisions in the field; Smaller, rapid-deploy COLTs that can be set up quickly to restore coverage in dense or hard-to-access areas; Hybrid portable generators that can extend uptime by 50%, conserving battery power and reducing refueling needs; Portable satellite kits using both low Earth orbit (LEO) and geostationary (GEO) satellite solutions support connectivity in the field and help restore network backhaul in challenging conditions. In 2025 alone, T-Mobile US, Inc. supported communities and first responders through more than 60 disaster events nationwide and deployed thousands of assets to help maintain connectivity, including thousands of generator deployments and refueling missions. T-Mobile US, Inc.’s AI-powered Self-Organizing Network (SON) continuously monitors network conditions and automatically adjusts performance in real time, rerouting traffic, optimizing signal strength and prioritizing critical connections when infrastructure is impacted so people can stay connected when they need it most. During Winter Storm Fern in January 2026, which impacted more than 30 states and left more than one million people without power, T-Mobile US, Inc.’s network remained resilient under pressure. With SON, the company was able to quickly adapt and prioritize connectivity in affected areas, helping keep network sites running for more than 250,000 additional minutes by conserving battery power and optimizing performance. Among customers that were impacted, 68% were reconnected within the first hour and 98% within eight hours. More recently, during Winter Storm Hernando and the torrential March storms in Hawaii, SON delivered more than 10,000 additional adjustments and extended connectivity across impacted areas, helping people stay in touch and access critical information. In some cases, these capabilities allow T-Mobile US, Inc. to streamline and expedite response and recovery without deploying additional equipment. During a tornado event, network teams remotely optimized coverage in about an hour, restoring service faster and reducing the need for on-site response. T-Mobile US, Inc. continues to expand connectivity beyond traditional infrastructure with satellite-based innovation, helping maintain communication during critical situations. When disasters struck in 2025, T-Satellite supported more than one million messages and connected hundreds of thousands of people when terrestrial networks were unavailable. During the devastating Texas flooding, it enabled hundreds of thousands of messages, providing a critical lifeline for impacted communities to reach loved ones and emergency services. More recently, during Winter Storm Fern, T-Satellite saw significant spikes in usage, supporting more than 250,000 users and 1.5 million messages as people connected with loved ones and stayed informed when traditional networks were unavailable. During the recent Kona storms, thousands more users relied on T-Satellite to help them stay connected. T-Satellite also enables Wireless Emergency Alerts (WEAs), with more than 100 alerts delivered during Winter Storm Fern alone, helping deliver critical safety information to compatible devices regardless of provider. Anyone who signs up can also access Text to 911 capabilities at no cost on supported devices. T-Mobile US, Inc. is also expanding satellite connectivity internationally, starting with Canada and New Zealand, enabling automatic connectivity abroad for customers with T-Satellite on compatible devices when cellular service isn’t available. Combined with deployable assets and drone-enabled capabilities, these solutions extend coverage into some of the most difficult-to-reach areas during emergencies, including remote and rural environments. T-Mobile US, Inc. also offers T-Priority, a dedicated solution for first responders built on T-Mobile US, Inc.’s 5G Advanced platform using network slicing technology, delivering prioritized connectivity and clearer connections during emergencies and times of congestion. Behind the scenes, real-time generator telemetry plays a key role in response efforts by giving teams live visibility into site conditions, including fuel levels and performance. This allows crews to prioritize resources, reduce downtime and keep sites running longer without needing to physically check each location, while new hybrid generators also extend uptime by up to 50%.
