Digital Equity Continued OUR COMPANY OUR GOVERNANCE OUR PEOPLE OUR COMMUNITIES THE ENVIRONMENT THE NUMBERS AND SMALL PRINT Closing the Digital Divide in California In 2021, T-Mobile continued to honor our commitment to the California Emerging Technology Fund (CETF) for contributions earmarked for digital literacy training and other digital inclusion programs for low-income and unconnected Californians. Breaking Down Barriers and Creating Opportunities for LGBTQ+ Youth As a longstanding partner of the Human Rights Campaign (HRC), we made a five-year commitment to support the HRC Foundation as it launches a new initiative to provide digital literacy and financial empowerment training and resources for disadvantaged LGBTQ+ youth, helping this vulnerable population lead safer, healthier lives. The training includes education about cyberbullying and internet safety, as well as the basics of budgeting and financial management. HRC’s new programming will provide critical understanding and new skills that can help disadvantaged LGBTQ+ youth lead healthy, productive lives. Helping Entrepreneurs Build their Skills with Magenta Edge With Magenta Edge , the mission is simple: to help small business owners get ahead. Founded in early 2021 with a focus on Black-owned small businesses that have been disproportionately impacted by COVID-19, Magenta Edge serves as a hub of original content to help small business owners learn and execute as they navigate the ups and downs of entrepreneurship. Magenta Edge provides educational programming, real stories, and insight for all entrepreneurs, and covers a range of business topics, from marketing and communications to business finances and digital taxes. It has featured successful small businesses we love here at T-Mobile such as Abbey Creek Winery, BOOMBOX Gym, REC Philly, ZEN Succulent and Big Mama’s Kitchen (pictured below clockwise from top left). To see videos featuring these small businesses, visit the Magenta Edge website. Going forward, the program’s content will continue to evolve and expand with a focus on ALL minority- owned small businesses. 379K Unique visitors engaged in the Magenta Edge curriculum in 2021 21K signed up for digital workshops Digital Workshops A workshop series where small businesses receive advice and best practices on a variety of topics in sessions led by industry experts.

EXTENDING A WELCOME TO REFUGEES WITH WELCOME.US Global unrest and conflict have created a massive refugee crisis. In countries like Afghanistan and Ukraine, families have been forced to leave their homes and begin the difficult process of rebuilding their lives in a new environment. For those who have left everything behind, connectivity is an essential lifeline to help them establish their new lives here in the U.S. That’s why, in early 2022, T-Mobile’s Mike Sievert joined 35 other CEOs from leading companies across business sectors to form the Welcome.US CEO Council. Through a unique public/private partnership model, newcomers to the U.S. are provided with urgently needed products, services, job training, and employment opportunities to help them begin their new lives. T-Mobile is contributing up to 200,000 lines of free, unlimited talk, text, and data for one year to help support incoming Afghan and Ukrainian refugees being resettled in the U.S. We are proud of this partnership and our contribution as it highlights the critical importance of our mission―to be the best in the world at connecting customers to their world. 2021 CORPORATE RESPONSIBILITY REPORT 46
