Boost SubscriberCo L.L.C., doing business as Boost Mobile, is an American telecommunications company and wholly owned subsidiary of EchoStar Corporation which operates as a mobile virtual network operator (MVNO) in the United States. Together with its sister brands Gen Mobile, it serves 7.51 million subscribers as of December 31, 2025. Boost Mobile was founded as a joint venture between Avalon Adderton, Peter Adderton, Craig Cooper, Kirt McMaster, and Nextel Communications in 2001. It was purchased by Nextel in 2003 and, as a result of the merger between Sprint Corporation and Nextel, then became owned by Sprint in 2005. It was then acquired by Dish Network on July 1, 2020, following the merger between Sprint and T-Mobile. After Dish's merger with EchoStar on December 31, 2023, Boost Mobile became a subsidiary of EchoStar. The company formerly operated a 5G network covering over 80% of the American population. However, it is no longer a facilities-based mobile network operator, having shut down its network on November 15, 2025 and instead became an MVNO hosted on AT&T's wireless network.
