T-Mobile US, Inc. traces its roots to the 1994 establishment of VoiceStream Wireless PCS as a subsidiary of Western Wireless Corporation. Spun off from parent Western Wireless on 3 May 1999, VoiceStream Wireless Corporation was purchased by Deutsche Telekom on 31 May 2001, for $35 billion and renamed T-Mobile USA, Inc. in July 2002. This legacy is reflected in some mismatch between US and German T-Mobile service, notably the frequency mismatch making phones inoperative in the other country, and picture messaging issues (non-delivery of pictures in text messages) between those networks.
