T-Mobile began as VoiceStream Wireless in 1994 and later adopted the T-Mobile brand after becoming part of Deutsche Telekom's U.S. operations. The company provides wireless voice, messaging, and data services, along with 5G home internet and business internet offerings for households and organizations. T-Mobile has also built a broader business around network evolution, including 5G-focused connectivity and managed connectivity, security, and fixed-wireless services for business customers.
