SpaceX has agreed to buy a nationwide 800 MHz low-band spectrum portfolio from Grain Management, the companies said on October 8, 2026. SpaceX says the spectrum will help its Starlink Mobile service become a major US mobile carrier. The deal is subject to FCC approval, and neither company has said what it costs.

What SpaceX is buying

Grain, an investment firm that specializes in digital infrastructure, says SpaceX will acquire 100% of its nationwide 800 MHz portfolio. Grain says the spectrum will support "next-generation satellite direct-to-device" services, and that the transaction is "subject to FCC approval and other customary closing conditions."

Grain also says it bought this portfolio from T-Mobile in August 2026, in exchange for cash and Grain's 600 MHz spectrum. Grain says the FCC approved that purchase in a July 2026 order.

SpaceX describes the licenses as up to 14 MHz of paired spectrum in the 800 MHz band, according to reporting by The Verge and CNBC. In its own words, quoted by CNBC, the spectrum "will pave the way for Starlink Mobile to become a major mobile carrier in the US."

What it means for a US phone user

Nothing in these announcements changes your service today. CNBC reports that T-Mobile, which promotes a satellite service called T-Satellite, has previously removed mention of Starlink from those promotions.

SpaceX has not said when Starlink Mobile service would start if regulators approve the deal. CNBC reports that SpaceX did not respond to a request for that timing.

The FCC has to sign off before SpaceX can use the licenses. Until then, the deal is a plan, not a network change.

SpaceX is pointing the plan at the big US carriers. The Verge says the planned network would be "directly competing with T-Mobile, AT&T, and Verizon," and its standfirst says SpaceX "snapped up low-band spectrum in a bid to take on T-Mobile, AT&T, and Verizon." CNBC reports that shares of AT&T, Verizon and T-Mobile "tumbled in extended trading," and that SpaceX "appears determined to battle telecommunications giants in the U.S., and deliver its own services without them." We did not find a published Starlink Mobile price or plan, so we are not comparing it with any carrier's satellite offer.

The limits

CNBC quotes Tim Farrar of TMF Associates, an industry expert: "But it's still a very limited amount of spectrum and to get reliable building penetration in urban areas SpaceX would have to deploy towers on the ground." CNBC adds that the spectrum "will help SpaceX combine satellite and ground-based coverage once it builds out a network of towers."

What we don't know

  • Price. Neither Grain's release nor the reports we read give a price for the spectrum. We found no Starlink Mobile plan price either.
  • Closing date. The deal is subject to FCC approval and other closing conditions. No closing date was given.
  • Regulator timing. No FCC decision date was given in the sources read.
  • Launch timing. SpaceX has not said when Starlink Mobile service would begin, and CNBC reports it did not respond to a request for that.
