Vodafone NTN: Inside Its Satellite IoT Strategy

For decades the mobile industry has been a terrestrial story: towers, fibre and microwave links mapped across the populated world. Yet most of the planet's surface, including oceans, deserts and remote land, still has no terrestrial mobile coverage at all. Industry estimates for the exact figure vary, but they commonly put the share of the Earth's surface with no cellular signal at around 85%. For anything that has to work everywhere, that gap has always been the ceiling.

Non-terrestrial networks close it. The important shift is not that satellites can carry data. It is that satellite links are being brought inside the same 3GPP standards that govern terrestrial mobile, so the same device and the same SIM can use both. Vodafone is one of the operators pushing this hardest, and it is doing so in two distinct ways that are easy to confuse. This article separates them.

What NTN actually is

Traditional satellite connectivity was an island. It needed specialist hardware, its own ground infrastructure and entirely separate service agreements. It was expensive and operationally awkward, and it did not talk to the cellular world.

3GPP, the body that standardises mobile networks, changed that with Release 17 in 2022, the first release with normative support for NTN. Crucially it introduced two separate strands. One is NR-NTN, extending 5G New Radio over satellite for broadband-style access, including direct-to-device services for handsets. The other is IoT-NTN, extending NB-IoT and LTE-M (eMTC) over satellite for low-power devices. Later releases build on this: Release 18 adds mobility and coverage enhancements, and Release 19 introduces features such as store-and-forward operation for delay-tolerant IoT and work on satellites that carry the base station themselves.

Two architectures matter here. In a transparent, or bent-pipe, payload the satellite simply relays the signal to a ground gateway, where the network core does the work. In a regenerative payload the satellite processes the signal itself. Most current deployments are transparent, which keeps the satellite simpler and pushes the intelligence to the ground.

Pillar one: direct-to-device broadband (AST SpaceMobile and SatCo)

The most eye-catching part of Vodafone's strategy is direct-to-device broadband through AST SpaceMobile, a company building satellites that behave like cell towers in orbit and connect to ordinary, unmodified smartphones. In January 2025 Vodafone made what it described as the first space-based mobile video call from an area with no terrestrial coverage, using AST's BlueBird satellites.

In 2025 the two companies formalised a jointly owned European satellite business called SatCo, headquartered in Luxembourg, to distribute AST's services to mobile operators across Europe under a single wholesale arrangement. Commercial services are targeted from 2026, and Vodafone has said operators covering 21 EU member states have expressed interest. Later in 2025 the partners announced a new EU satellite constellation and selected Germany for a sovereign satellite operations centre, with an ITU filing made through Germany and a "command switch" intended to give European oversight of the service.

A common misconception is that this runs on a single fixed band such as 900MHz. In practice the service is designed to use the mobile operators' own licensed spectrum, and the partners have also positioned the constellation as a candidate for the EU 2GHz mobile satellite services band. The point of D2D is not a special satellite phone. It is that an existing handset, on an existing tariff, can keep a connection where the terrestrial network stops.

Pillar two: NB-IoT over satellite (Skylo)

The second pillar is aimed squarely at IoT. In January 2026 Vodafone IoT announced a partnership with Skylo Technologies to bring NB-IoT NTN satellite connectivity to customers. Skylo does not own satellites; it runs a standards-based NTN network, using existing satellite operators, that spans 36 countries and around 70 million square kilometres of coverage.

The design is the important part. Vodafone and Skylo are integrating their network cores so a device can switch between terrestrial cellular and satellite using a single Vodafone SIM, with the satellite acting as an overlay to existing coverage. It is built on 3GPP Release 17, works with standard IoT hardware and is managed through Vodafone's existing Managed IoT Connectivity Platform, so customers see one interface across both paths. The initial phase is a trial, with a full commercial service intended to follow. Vodafone points to asset tracking, energy services, environmental monitoring and fleet management as the early use cases.

Why two different approaches?

Because a smartphone and a battery-powered sensor are not the same problem. One needs enough bandwidth for voice, messaging and eventually video; the other needs to send a few bytes reliably on a power budget measured in years. Trying to serve both with one design would compromise both.

Both are standards-based, and that is the strategic thread. An IoT device designed for cellular can add satellite support without a separate proprietary modem, chipset, subscription and management system. For anyone choosing a satellite IoT platform now, a 3GPP-compliant path is the safer bet than a closed one.

What it means for an IoT deployment

The practical value of NB-IoT NTN is resilience and reach rather than throughput. A few things follow directly from how the technology works:

• Coverage becomes a fallback, not a fixed line. A device in range of a tower uses it; out of range, it can use the satellite. That suits assets that move through coverage gaps or sit in remote locations.
• It is narrowband and delay-tolerant. Expect modest data rates and higher latency than terrestrial NB-IoT, with geostationary links adding more delay than low-orbit ones. This is for telemetry, status and alerts, not video.
• Devices need GNSS. NB-IoT NTN modules require a satellite positioning receiver to manage timing and Doppler, which affects power budget and antenna planning.
• The management stays familiar. Because it runs through the same Vodafone platform and SIM, the estate does not fragment into a separate satellite silo.

Where it fits, and where it does not

NTN earns its place in specific settings: remote industrial sites off the terrestrial map, maritime and cross-border logistics, environmental and utility monitoring in the field, and failover for critical telemetry that cannot go dark during a terrestrial outage. Agriculture across large landholdings is a natural fit for narrowband sensors that would otherwise need a local gateway.

It is not a replacement for terrestrial mobile. In dense urban areas, buildings block satellite signals and 5G comfortably out-performs any satellite link on throughput. Vodafone is not trying to replace the network on the ground. It is filling the gaps the ground network was never going to reach economically.

Regulation, spectrum and sovereignty

Spectrum is where satellite-to-device gets politically interesting. Because the service reuses terrestrial mobile spectrum from orbit, it has to be coordinated with national regulators such as Ofcom in the UK to avoid interference with ground networks, and licensing differs country by country. The AST and Vodafone constellation has been positioned around national operator spectrum plus a potential EU 2GHz mobile satellite services band, with an ITU filing made through Germany.

The sovereignty angle is deliberate. Locating the SatCo headquarters in Luxembourg and the operations centre in Germany, and building in a "command switch" for European oversight, is aimed at keeping control of a strategic communications layer within Europe rather than depending entirely on non-European systems. For infrastructure and public-sector IoT, that governance question is not a side issue.

What to check before you build on NTN

If satellite fallback is part of your plan, a few questions save trouble later:

• Is the service commercially live in your target countries yet, or still in trial?
• Does your chosen module support NB-IoT NTN and include the required GNSS receiver?
• Are your data rate and latency expectations realistic for narrowband satellite links?
• Is the connectivity managed through one platform and SIM, or does it fragment your estate?
• What is the commercial model for satellite bytes versus terrestrial, and how is failover billed?
• How does provisioning work, and does eSIM or SGP.32 give you room to change provider later?

The bigger picture

Vodafone's two-track approach is a good map of where satellite connectivity is going. Broadband D2D will make "no signal" rarer for people; NB-IoT NTN will make "out of coverage" rarer for machines. Both are being folded into the same standards and, in Vodafone's case, the same management platform, so satellite stops being a separate world and becomes another band the network can reach for.
