T-Mobile was originally founded as a subsidiary of Deutsche Telekom AG in 1990, operating under the name 'Deutsche Telekom' in Germany. The brand was established to provide mobile telecommunications services and quickly expanded into various markets in Europe and the United States. In 2001, T-Mobile USA was formed, and over the years, the company has grown through strategic acquisitions, including the merger with Sprint in 2020, solidifying its position as one of the largest wireless carriers in the United States.
