Description of Business
We are the Un-carrier(TM). Un-satisfied with the status quo. Un-afraid to innovate. T-Mobile is the fastest growing wireless company in the U.S., based on customer growth in 2014, currently providing wireless communications services, including voice, messaging and data, to over 55 million customers in the postpaid, prepaid, and wholesale markets. The Un-carrier proposition is an approach that seeks to listen to the customer, address their pain points, bring innovation to the industry, and improve the wireless experience for all. In practice, this means offering customers a great service on a nationwide 4G Long-Term Evolution ("LTE") network, devices when and how they want them, and plans that are simple, affordable and without unnecessary restrictions. Going forward, we will continue to listen and respond to our customers, refine and improve the Un-carrier proposition, and deliver the best value experience in the industry.
