OUR COMPANY OUR GOVERNANCE OUR PEOPLE OUR COMMUNITIES THE ENVIRONMENT THE NUMBERS AND SMALL PRINT Disaster Relief When Disaster Strikes, Connecting People Is Our Priority Disasters wreak havoc when they strike, making connectivity paramount to first responders, local authorities, and impacted communities. We prepare year-round for disaster scenarios to be ready at a moment’s notice with critical network support and connectivity supplies. Thanks to our distributed model of warehouses around the country, we can quickly deploy supplies and our emergency management fleet, including satellite- enabled vehicles, mobile command centers, Cells on Wheels (COWs) and Cells on Light Trucks (COLTs), to impacted areas. Vehicles can be almost anywhere in the U.S. within 12 hours to set up charging stations and provide other much-needed personal cellular supplies. In 2021, we utilized this model to respond to everything from flooding in Tennessee and tornadoes in Georgia and Kentucky, to Hurricane Ida in Louisiana, and a search and rescue in Washington. $2.9M worth of in-kind products and services for disaster relief efforts provided To enhance safety protocols for our employees, we established a virtual command center in 2021 in partnership with Everbridge. This allows us to quickly identify employees and buildings in areas impacted by disasters and connect with them quickly through a mass identification tool. In addition to these initiatives, we are improving our network resiliency by implementing a multi-year network hardening plan, making sure our network is ready for all types of emergencies and natural disasters. We’re investing in constant testing and improvements to our network’s backup and response systems including thousands of generators, advanced relief and recovery tools, and coordination and mobilization plans for supporting customers and their communities in critical times. Our Network Operations Centers (NOCs) run 24/7 during natural disasters, allowing our experienced technicians and engineers to monitor our network traffic demands and weather impacts in real time. Disasters all have the same backbone. They just have different arms and different feet. A wildfire is slightly different than a hurricane, which is different than civil unrest, which is completely different than COVID or an earthquake or volcanic eruption. The one constant is the help needed.” Becky Romero Senior Manager, Business Continuity, T-Mobile 2021 CORPORATE RESPONSIBILITY REPORT 50
