What happens next, and how you would know
Six parts of evidence lead to one question a board will ask: does SpaceX become a mobile carrier, or stay a supplement to one?
Sources: Company releases, FCC orders and filings, SEC filings, and trade reporting where marked. Retrieved 17 Sep 2026.
On the public evidence, neither of the two scenarios below is more likely than the other, and no probability attaches to either. What can be established is what each path requires, what the two sides are publicly asserting, and what you would observe first if either were happening.
The six ways to sell mobile service from orbit
The six models below are sorted by how real each one is, which is not the same as how much each one is discussed. That sorting is our own judgement; the status attached to each row is not. It comes from FCC orders and the FCC licence file for the licensed rows, from ET Docket 26-169 for the proposed rulemaking, and from company statements reaching us through trade reporting for the rest.
| Model | Who owns the customer | Status |
|---|---|---|
| Wholesale SCS over a carrier’s spectrum | The carrier | Live and licensed. T-Mobile/Starlink; AT&T and Verizon with AST (part 1) |
| Facilities-based carrier on owned spectrum | The satellite operator | Permitted and stated. FCC tech-neutral waivers, 12 May 2026; SpaceX has said it intends to (part 5) |
| Small cells at customer premises, satellite backhaul | The satellite operator | Described publicly by SpaceX; no filing. Dismissed on the record by T-Mobile |
| MVNO onto an incumbent network | Shared, badly | Publicly declined by each of the three carriers in 2026; see below on executive remarks |
| Unlicensed direct-to-device | Whoever ships the device | Proposed rulemaking. ET Docket 26-169 |
| WiFi offload as a satellite play | n/a | Commentary only. We found no announcement or filing by anyone |
The MVNO row is the one most often assumed and least supported. Each of the three incumbents has separately said in public that it is not offering one to a satellite operator, and those statements reach us through trade reporting rather than through transcripts. They are three separate refusals rather than one industry position stated once.
An MVNO is the cheap way into mobile, and the expensive way is the one now on the table.
The remarks attributed to named executives here were made at investor conferences and on earnings calls during 2026 and reach us through trade reporting: Light Reading, Fierce Network, RCR Wireless and telecoms.com. We have not obtained transcripts. They are the only public statements of intent available, and they are marked throughout as reported rather than verified. Anything load-bearing should be checked against a transcript before it is quoted onward.
Reported Executive remarks cited above: SpaceX Q2 update, 5 Aug 2026, as reported by RCR Wireless; T-Mobile’s CFO, Citi Global TMT Conference, September 2026, as reported by Light Reading; AT&T’s CEO, Goldman Sachs Communacopia + Technology Conference, September 2026, as reported by telecoms.com; Verizon’s CEO, Q2 2026 earnings call, 24 July 2026, as reported by Fierce Network. No transcripts obtained; paraphrased rather than quoted where marked, and reported rather than verified.
What each scenario requires
Scenario A: SpaceX becomes a facilities-based carrier
SpaceX already has the regulatory permission and, from late 2027, the spectrum. What it still needs is unglamorous: cell sites and backhaul, handset support for its bands, retail distribution, billing and care, and the hardest of them, indoor coverage, which is why the small-cell idea exists at all. Its own executives have described putting “a cellular base station on the gear that holds a Starlink broadband dish” and deploying “little femtocells around the country”, with service “end of next year”. Remarks made at the SpaceX Q2 update on 5 Aug 2026 and reported by RCR Wireless rather than verified from a transcript.
That approach is a genuine architectural argument, not a joke: it converts a subscriber’s existing dish into a site, and it substitutes distributed capex for a low-band spectrum position. It is also the claim the incumbents attack hardest. T-Mobile’s CFO, speaking at the Citi Global TMT Conference in September 2026 and reported by Light Reading rather than verified from a transcript, said the approach would need on the order of a billion femtocells to match existing outdoor coverage, with the interference and backhaul problems that implies. That figure reaches us as a paraphrase of a spoken remark rather than as a quotation.
Scenario B: SpaceX stays supplemental
Scenario B is also coherent, and cheaper. The economics from part 2 still work: the carrier lends spectrum, adds coverage it cannot economically build, and bills its own subscriber. It is also the only one of the two that the table above records as live and licensed.
What that path costs is a ceiling. It caps the business at a wholesale margin on someone else’s customer, metered through the 5–6 MHz service channel set out in part 3. It would also mean $19.6B of nationwide spectrum bought to run a supplement, which is a strange use of the asset.
The three hinges
Everything turns on three things, and each of them is checkable rather than rhetorical. The first is whether the service works indoors, the second is whether the spectrum position is deep enough to carry a national network, and the third is what the capital and the regulatory clock require. None of the three is settled by an opinion about anyone’s intentions.
1. Indoor coverage
Every incumbent argument reduces to this. AT&T’s CEO, speaking at the Goldman Sachs Communacopia + Technology Conference in September 2026 and reported by telecoms.com rather than verified from a transcript, framed satellite as solving the last 2% of coverage rather than offering a new way to serve the other 98%. Verizon’s CEO, on the Q2 2026 earnings call of 24 July 2026 and reported by Fierce Network on the same unverified basis, has described terrestrial networks as orders of magnitude more efficient than satellite and put the addressable market at single-digit millions of rural homes. Both are paraphrases of spoken remarks rather than quotations.
The propagation difference behind those arguments is real and runs their way: SpaceX’s owned spectrum sits at 1.7–2.2 GHz, worse for wall penetration than the 700 MHz AST leases (part 3). We have not modelled link budgets, so we cannot adjudicate the claim, but the frequencies are public, and the physical argument is consistent with them. If SpaceX solves indoor coverage, the architecture that does it is terrestrial small cells, not satellites.

2. Spectrum depth
65 MHz nationwide is a real position, on the order of what a single large carrier deploys in one mid-band layer. Whether that is enough depends entirely on where: the same 65 MHz behaves very differently in a rural county and in Manhattan, and we have not modelled either. It is a question to put to a capacity model.
3. Capital and the clock
Part 6 showed the money is arriving from outside the industry, which settles the capital half of this hinge and leaves the clock. The FCC’s news release accompanying its approval of the EchoStar transactions on 12 May 2026 describes performance obligations requiring “meaningful, reliable connectivity to the public — whether D2D, terrestrial, or both — within years”, but publishes no numeric threshold or deadline. Until the order’s specific terms are read, the size of that obligation is unknown; what is clear is that one exists and is technology-neutral.
The incumbents’ answer is already in the record
On 14 May 2026, AT&T, T-Mobile and Verizon announced a joint venture for satellite direct-to-device: pooled spectrum, joint investment and common technical specifications, with existing individual satellite agreements left in place (joint release). That is a company announcement rather than a regulatory filing, and it should be read at that weight. It is explicitly an agreement in principle: no name, no ownership split, no named satellite partner, no timeline, and we found no regulatory filing for it.
Taken at face value, the release describes three carriers pooling spectrum and agreeing common technical specifications for satellite direct-to-device, the same asset class part 4 identified as the one an entrant cannot assemble quickly. Whether it changes the market depends on terms that have not been published, and on a regulatory review that, as far as we can find, has not begun. Any reading of motive beyond the release is commentary, and we are not offering one.
What you would observe first
None of what follows requires inside information. The indicators in the two tables below are ours rather than anyone else’s, but each one is a public filing, registration, certification or disclosure that would appear before a strategy is announced. They are the things that happen before the press release rather than after it.
| If Scenario A is happening | Where it shows up |
|---|---|
| Terrestrial build begins | FCC licensing and special temporary authority activity for SpaceX at 1695–1710 / 2000–2020 / 2180–2200 MHz |
| Device support lands | Handset band certifications for the AWS-4, H-block and unpaired AWS-3 ranges |
| Sites get real | Tower and rooftop lease announcements; ASR registrations; small-cell siting applications |
| Retail intent | A consumer brand, number portability, care and billing hiring |
| The lease relationship cools | The 173 PCS G-block lease records changing, or not being renewed |
| If Scenario B is happening | Where it shows up |
|---|---|
| The partnership renews | T-Mobile disclosure after the exclusivity period; continuation of the wholesale arrangement |
| The spectrum stays in orbit | No terrestrial filings; the 65 MHz used only for supplemental coverage |
| The JV converts | Definitive agreements, a named entity and a regulatory filing for the three-carrier venture |
Neither table is a forecast, and neither is a scorecard to be totted up. Each is a list of the things that would have to become visible in public before either path could be executed.
Two dates anchor the whole thing: the EchoStar–SpaceX second closing, expected on or about 30 November 2027, and AST’s 1,197 leases expiring 9 May 2028. Between them sits every commercial negotiation in this market.

What this tells you
Carrier strategist
build the JV question into your own planning now, whether or not you are in it. If three national carriers pool satellite spectrum, the terms available to everyone else change, and regional operators are not at that table.
Investor
the indicator tables above are a diligence checklist. A company that says it will build a terrestrial network and has filed nothing, certified nothing and leased no sites is at the intent stage, whatever the roadmap slide says.
Vendor
both scenarios buy equipment, but different equipment. Scenario A is small cells, backhaul integration and multi-band devices. Scenario B is payloads and gateways. The bands are public and the same in both: the owned, contracted 1695–1710, 1915–1920, 1995–2000, 2000–2020 and 2180–2200 MHz, 65 MHz in all, plus the leased PCS G block at 1910–1915 / 1990–1995 MHz.
Method and limits
How this was built
Transaction terms, spectrum holdings and financials come from FCC orders, the FCC licence file and SEC filings, as cited through the series. The joint-venture description comes from the carriers’ own release, and we describe only what that release says.
Executive remarks were made at investor conferences and on earnings calls and reach us through trade reporting; we have not obtained transcripts. Where we could not pin an outlet and a date to an exact form of words, we have paraphrased rather than quoted.
What it does not show
The two scenarios are analytical constructions, not forecasts, and we attach no probabilities to them: the evidence supports both readings today, which is precisely why the observable indicators matter more than an opinion.
The absence of a regulatory filing is not proof that none exists. Nothing here is investment advice, and no company’s securities are valued or recommended.
