Starlink Mobile took its clearest step yet toward becoming a US mobile carrier on Oct. 8, when SpaceX announced an agreement to acquire 100% of Grain Management’s nationwide 800 MHz spectrum portfolio. The company says the low-band licenses address one of the key remaining technical gaps between satellite-to-mobile service and a full carrier network, but the deal still needs FCC approval before anything changes for customers.
What SpaceX is buying
SpaceX describes the portfolio as up to 14 megahertz of paired spectrum in the 800 MHz band, licensed nationwide. Low-band spectrum like this travels farther and passes through buildings more easily than the higher frequencies carriers use for capacity, which is why it matters for indoor coverage. SpaceX says most existing mobile devices already support the band, so the phones customers own would be the starting point rather than new hardware.
The licenses were not long on Grain’s books. Grain Management, a digital infrastructure investment firm, bought the same portfolio from T-Mobile in August 2026 in exchange for cash and its own 600 MHz licenses, after an FCC order in July 2026 approved that purchase with a competitive process and a conditional pathway for satellite direct-to-device use. Grain says this sale fits that framework. Neither company disclosed the price.
The arrangement is not final. SpaceX says it will deploy a hybrid architecture only once it receives final FCC approval, combining its satellite-to-mobile constellation with an advanced terrestrial deployment. Its filing for the transaction describes that ground network: radios feeding sectorized antennas on towers, rooftops and other structures. The filing cites the FCC coverage benchmarks attached to the licenses, but those are regulatory deadlines, not a consumer launch schedule.
The FCC cleared the satellites this week, too
The FCC adopted that authorization Oct. 6, granting SpaceX call sign S00735 for 15,000 non-geostationary satellites providing mobile satellite service and supplemental coverage from space in the United States, direct-to-cell service outside it, and fixed-satellite backhaul. SpaceX says its V2 Starlink Mobile satellites will deliver more than 100 times the bandwidth of the generation behind today’s service, and that the order also clears the full range of Ka, V, E and W band backhaul its V3 broadband satellites use, so the new fleet can work with existing gateways.
SpaceX says the 2 GHz mid-band airwaves it already holds will provide high-bandwidth capacity, while the new low-band licenses provide a coverage layer whose signal penetrates obstacles such as walls. The FCC assigned that mid-band spectrum to SpaceX in an order adopted May 12, 2026, approving the assignment of EchoStar’s AWS-4, AWS-H Block and unpaired AWS-3 licenses.
The 800 MHz portfolio stacks coverage on top of that capacity. “With this new low-band spectrum and our Gen2 constellation, Starlink Mobile can now become the first network operator to deploy both satellite and terrestrial spectrum,” SpaceX said in the announcement.
That leaves a window the incumbents are trying to fill. AT&T, T-Mobile and Verizon jointly stood up a satellite venture with a chief executive and no launch date, while Amazon Leo keeps adding countries to its low-Earth-orbit broadband service.
What buyers still don’t know
Plenty, and none of it is settled by this agreement. Neither company disclosed the agreed purchase price. The Wall Street Journal, citing people familiar with the matter, reported it is about $8 billion in cash; neither company has confirmed that figure.
There is also no announced retail Starlink Mobile plan for US customers: no price, no data limits, no eligibility terms and no launch date, and the filing names no specific radio vendors or tower partners. FCC approval is the first real gate, and this agreement does not itself launch a new consumer service.
