T-Mobile provides mobile wireless communication services through a variety of service plan options, including the popular Go5G Plus with unlimited talk, text, and data.

The company sells a wide selection of wireless devices (smartphones, wearables, tablets, home broadband routers) from various manufacturers. A key offering is High-Speed Internet, a fixed wireless product leveraging their 5G network capacity. T-Mobile also provides device protection, financial services, and advertising.

T-Mobile operates as a single business segment, providing wireless services to three primary customer categories: Postpaid (77% of service revenue), Prepaid (15% of service revenue), and Wholesale and other services (8% of service revenue).

T-Mobile's "Un-carrier" strategy centers on customer experience and disrupting traditional industry practices. Key initiatives include eliminating pain points like contracts and overages, and investing in the largest and fastest 5G network. The company aims to be "Famous for Network" by leveraging its multi-layer spectrum portfolio. Growth strategies include expanding 5G coverage and capacity, offering innovative products like High-Speed Internet, and focusing on customer retention. T-Mobile actively seeks opportunities to acquire spectrum licenses and other assets to enhance its competitive advantage and expand service offerings.

T-Mobile operates in the highly competitive wireless communications services industry as the second largest provider in the U.S. based on total postpaid and prepaid customers. Key competitors include AT&T, Verizon, and DISH, as well as smaller regional providers and cable companies offering wireless services through MVNO agreements. Competition is based on factors such as network quality and capacity, customer service, pricing, marketing, and innovative product offerings. Some competitors differentiate through discounted pricing or bundled services.

• Competition: Intense competition in the wireless communications services industry, especially as the market saturates, puts pressure on pricing and margins. T-Mobile's ability to attract and retain customers is crucial.
• Cybersecurity: The company is vulnerable to cyberattacks and data breaches, which could disrupt operations, lead to financial losses, and damage reputation. The August 2021 cyberattack and January 2023 data breach highlight this risk.
• Technology Development: Failure to keep pace with technological advancements could lead to declining demand and challenges in implementing business strategies.
• Spectrum Acquisition and Regulation: The scarcity and cost of wireless spectrum, along with regulations on its use, could impact T-Mobile's ability to expand and maintain its network.
• Reliance on Key Personnel: T-Mobile's success is dependent on its ability to retain and motivate key personnel, and its ability to hire qualified replacements. Loss of key personnel could negatively impact the business.
