SpaceX moves to turn Starlink into U.S. mobile carrier with low‑band spectrum
SpaceX announced on Oct. 9, 2026 that it will acquire a nationwide portfolio of up to 14 megahertz of paired low‑band spectrum in the 800 megahertz band, a step that would allow its Starlink satellite constellation to operate as a major U.S. mobile carrier.
The acquisition is intended to add a low‑band coverage layer that can travel long distances and pass through walls, complementing Starlink’s existing 2 GHz mid‑band spectrum. SpaceX says most current mobile devices already support the under‑used 800 MHz band, enabling service without hardware modifications.
Elon Musk posted on X that the low‑band spectrum represents “the last critical piece of the spectrum puzzle needed for SpaceX to provide complete phone coverage in America.” The company’s press release adds that, once the Federal Communications Commission gives final approval, Starlink Mobile will combine satellite‑to‑cell services with an advanced terrestrial architecture to deliver high‑speed service directly to unmodified devices.
Industry reaction was swift. After hours of trading, AT&T fell 7.3%, while Verizon and T‑Mobile each slipped 6.6%. SpaceX’s stock rose 1.5% on the news. TD Cowen analyst Gregory Williams warned that SpaceX’s entry could be “highly bearish for the wireless industry.”
SpaceX also highlighted a new patent (US 12,757,141 B1) that details how its satellites will synchronize narrow beams to ensure a steady signal delay for phones, addressing a technical challenge that can cause calls and data to slip out of step.
There are still questions about real‑world performance. AT&T CEO John Stankey noted that low‑band signals may struggle to penetrate high‑rise buildings or large stadiums, emphasizing the need for further testing once the network is live.
With more than 11,100 Starlink satellites already in low‑Earth orbit and a planned launch of 15,000 next‑generation satellites, the company is poised to expand its footprint quickly if regulatory clearance is granted.
The next milestone is the FCC’s final decision, which will determine when Starlink Mobile can begin commercial service and how aggressively it will challenge the existing telecom giants.
