US Mobile

US Mobile is a New York-based mobile virtual network operator that lets customers build their own wireless plans and switch between Verizon, AT&T, and T-Mobile on a single line. Branded internally as Warp (Verizon), Dark Star (AT&T), and Light Speed (T-Mobile), its 'Teleport' multi-network technology and eSIM-first approach have pushed it toward a self-styled 'Super Carrier' that now also bundles Starlink home internet. Founded in 2015 by Ahmed Khattak, it has grown from a niche unlocked-phone reseller to roughly a million customers.
