Two numbers landed in the same news cycle this month, and neither made much sense without the other. Travel eSIM usage hit 134 million users globally in 2026, up 32% from 101.8 million the year before, running 70–80% cheaper than traditional roaming. In the same week, AST SpaceMobile secured temporary FCC authority to test direct-to-device satellite connectivity in the 800 MHz band in the US, backed by AT&T and Verizon — while across the Atlantic, a carrier-neutral joint venture called Satellite Connect Europe was already running live network-integration tests with Vodafone, Orange, Deutsche Telekom, and Telefónica across eight European countries.
Read separately, these are two unrelated infrastructure stories. Read together, they're the same story: the layer that used to define which network you were "on" is dissolving from two directions at once, and it's worth understanding what that actually means before it becomes obvious in hindsight.
What actually happened
eSIM adoption's growth curve is no longer a projection — 134 million travel eSIM users is a real, current number, and the price gap driving it is stark: Airalo's most popular Europe plan runs about $4.50 for 1GB over seven days, against $10–12 per day for a major US carrier's international pass. That's the roaming-margin story I've written about before, and it's now fully mainstream, not an early-adopter niche.
The satellite side moved just as fast, but through a more unusual structure. AST SpaceMobile's US test authority — a 30-day window covering up to 100 commercial devices in the 817–824 MHz and 862–869 MHz bands — is explicitly a testing milestone, not a commercial launch, and it sits alongside AST's existing partnerships with AT&T and Verizon. The more structurally interesting development is on the European side: Satellite Connect Europe, a genuine joint venture between Vodafone and AST SpaceMobile headquartered in Luxembourg, isn't owned or operated by a single carrier. It's built explicitly as wholesale, carrier-neutral infrastructure that any European mobile operator can plug into — Orange has already announced testing in Romania through the JV, and Vodafone's own national units in Portugal and Spain have both pointed to commercial launch around 2027, not this year, which is a more realistic timeline than some coverage has implied.
Why the "carrier-neutral" detail changes the story
Here's the part worth sitting with. A lot of the commentary around satellite direct-to-device technology carries an implicit doom narrative for smaller players: if satellites can connect any phone anywhere without a terrestrial network at all, what happens to MVNOs, resellers, and eSIM-first brands that depend on wholesale access to someone else's network?
The Satellite Connect Europe structure suggests a different answer. A carrier-neutral joint venture, deliberately built to sell wholesale connectivity to multiple operators rather than being owned outright by one, is not the architecture of a company trying to eliminate resellers — it's the architecture of a company trying to become the substrate other brands build on top of. That's a meaningfully different outcome than "satellite kills MVNOs." It looks more like MVNO 3.0: instead of reselling access to one terrestrial network, the next generation of lean, eSIM-first operators could resell access to a blended terrestrial-plus-satellite layer, switching between whichever is available and cheapest in real time, with the customer never needing to know or care which one they're actually using.
The realistic timeline, not the hyped one
It's worth being precise about what "testing across eight countries" and "temporary FCC authority" actually mean for the next 12–24 months, because the gap between the current milestone and a consumer-ready product is still real. AST's US authorization is explicitly non-commercial and time-boxed to 30 days. Satellite Connect Europe's own operator partners are pointing to 2027 for commercial availability, not late 2026. What's happening right now is integration testing — proving the satellite layer can hand off cleanly with existing terrestrial networks using ordinary smartphones, no special hardware — which is a necessary and genuinely significant step, but it's infrastructure validation, not a product travelers will be buying next month.
The strategic fork for MVNOs and eSIM brands
This is where the timeline actually matters operationally, not just academically. Providers in the eSIM and MVNO space have a real choice to make now, not once satellite connectivity is commercially live: build toward satellite-agnostic, multi-network switching as a design principle today, or wait until the technology is proven and retrofit later.
Waiting isn't free. If Satellite Connect Europe's wholesale model becomes the default substrate for blended terrestrial-satellite connectivity across Europe by 2027–2028, the operators and eSIM brands with the technical and commercial relationships already in place will have a real head start over those trying to integrate a new connectivity layer into an existing product after competitors have already normalized it for customers. Positioning early doesn't require betting the business on a 2026 launch that isn't coming — it means treating "which underlying network" as an increasingly irrelevant implementation detail in how a product is built, starting now.
What's left for incumbent telcos to differentiate on
Step back, and the compounding effect of these two disruptions landing in the same news cycle is the real story. eSIM has already commoditized roaming margins — the premium that used to justify sticking with your home carrier abroad is mostly gone. Satellite direct-to-device, if the carrier-neutral wholesale model holds, is on track to commoditize coverage itself — the idea that being with a specific network determines whether you have signal at all.
Between those two forces, the list of things a traditional mobile operator can still meaningfully differentiate on gets shorter: network quality and latency in dense urban use, enterprise and IoT relationships, brand trust, and — the theme I keep returning to in this column — actual human support when something goes wrong, rather than a chatbot queue. Infrastructure ownership alone is no longer the moat it used to be. What operators, MVNOs, and eSIM brands do with the connectivity, once having it stops being the differentiator, is where this all actually gets decided.
