Space X “direct-to-cell” service to start in the U.S. this fall, but with what wireless carrier?
In a May 30th filing with the FCC, SpaceX wrote that it “looks forward to launching commercial direct-to-cellular service [1.] in the United States this fall.” That will presumably be only for text messages, because the company has stated that ONLY text will available in 2024. Voice and data won’t be operational until 2025.
Importantly, SpaceX did not identify the telco who would provide Direct-to Cell satellite service this fall.. Mike Dano of LightReading has suggested it might be T-Mobile US (more below), but there is nothing on the company’s news website to confirm that.
Note 1. “Direct to Cell works with existing LTE phones wherever you can see the sky. No changes to hardware, firmware or special apps are required, providing seamless access to text, voice and data,” according to the Starlink’s website. “Starlink satellites with Direct to Cell capabilities enable ubiquitous access to texting, calling, and browsing wherever you may be on land, lakes, or coastal waters. Direct to Cell will also connect IoT devices with common LTE standards.”

SpaceX disclosed its commercial direct-to-cell launch plans in a filing with the FCC that urged the Commission to make changes to its initial supplemental coverage from space (SCS) ruling. SpaceX argued the FCC should create SCS rules that are specific to each band of spectrum used in such offerings
In its most recent FCC filing, SpaceX said that “supplemental coverage from space (“SCS”) will enable ubiquitous mobile coverage for consumers and first responders and will set a strong example for other countries to follow.”
Furthermore, SpaceX said the “FCC should reconsider a single number in the SCS Order—namely, the one-size-fits-all aggregate out-of-band power flux-density (“PFD”) limit of -120 dBW/m2 /MHz that it adopted in the new Section 25.202(k) for all supplemental coverage operations regardless of frequency band.
If the Commission decides to retain an aggregate limit, adopting band-specific limits that efficiently and transparently achieve the accepted ITU interference protection threshold for terrestrial networks of -6 dB interference-to-noise ratio (“I/N”) would better achieve the Commission’s goals of ensuring better service, broader coverage, and more choices for consumers.
By making this simple adjustment to the SCS Order, the Commission can potentially bring an order of magnitude better service to consumers who use supplemental coverage from space in higher frequencies, without causing any risk of harmful interference to terrestrial services in adjacent bands,” SpaceX added.

SpaceX established a phone-to-satellite agreement with T-Mobile in 2022. That agreement called for the satellite launch vendor to add T-Mobile’s spectrum into its Starlink satellites. T-Mobile officials have suggested SpaceX’s satellite service might be included in its more expensive service plans for no extra charge, or through an extra fee on its other plans.

Sidebar: SpaceX LEO Satellites in Orbit
SpaceX currently operates a constellation of more than 6,000 Starlink satellites. That web of satellites helps to keep Starlink’s services consistent for users on the ground. Each Starlink LEO satellite travels extremely fast such that it goes around the world every 90 minutes.
SpaceX has stated that it plans to have around 800 satellites capable of direct-to-cell connections in orbit within a few months.
According to one source, SpaceX has so far launched more than three dozen satellites that support those “direct-to-cell“ connections.
