MobileStar Network ceased operation in October 2001, but its bankrupt assets and contracts were bought by Voicestream Wireless and by February 2002, was operating as T-Mobile Broadband. T-Mobile Broadband was the first part of VoiceStream to rebrand to the T-Mobile name. It was officially launched as T-Mobile HotSpot in August 2002.[5] Many of the original MobileStar Network employees still work for T-Mobile Hotspot and have been responsible for its expansion.
