Starlink Mobile enters the Western Balkans: the hard part is not the satellite

4iG and SpaceX plan direct-to-device services in Hungary and the Western Balkans. The commercial question is whether spectrum, resilience and wholesale integration can follow.

4iG Group and SpaceX have signed agreements to bring Starlink’s direct-to-device service to Hungary and parts of the Western Balkans. The announcement is notable not because a satellite can reach a handset—coverage demonstrations have already made that clear—but because a regional terrestrial operator is tying satellite-to-mobile connectivity to its own mobile businesses and to a separate government-facing security service. The decisive question is whether a satellite overlay can become an authorised, supportable part of a carrier network rather than an emergency link that sits outside it.

4iG says the first-generation Starlink Mobile service is planned for Hungary and Albania. A later Starlink Mobile V2 service is planned for Hungary, Albania, Montenegro and North Macedonia, using SpaceX’s global 2 GHz priority rights and targeting 5G non-terrestrial-network capabilities (4iG’s announcement). Bulgaria is not listed among those initial markets. That omission is not a verdict on the technology; it is a reminder that direct-to-device coverage is a regulatory and commercial product, not simply a footprint on a satellite map.

A two-stage plan, not one rollout

The agreement describes two materially different services. The first-generation service connects compatible LTE phones directly to Starlink satellites, without dedicated satellite equipment. 4iG presents it as a complement to its mobile networks in places with limited terrestrial coverage and as a fallback during emergencies or temporary outages. The company says the timing will depend on regulatory, technical and commercial conditions in each market (4iG).

V2 is a more ambitious proposition. 4iG says the future service will operate with SpaceX’s 2 GHz priority rights and enable 5G non-terrestrial-network capabilities in four countries. That language should not be read as a published launch date, a guaranteed data rate or a replacement for terrestrial radio access. The release gives no committed RFS date for the mobile service, no coverage obligation, no handset list, no service-level target and no retail or wholesale pricing.

Those missing details matter for operators. Direct-to-device systems face a constrained link budget: a satellite must reach a conventional handset with limited antenna gain, while sharing spectrum with terrestrial users and managing moving cells. The practical service envelope will depend on handset compatibility, satellite capacity, elevation, terrain, weather, network prioritisation and the amount of spectrum that can be used in each national market. A message or low-rate data session in a coverage gap is a different product from a substitute for a fibre-fed 5G site.

The sovereign service is a separate risk category

Alongside Starlink Mobile, 4iG Space and Defence Technologies and SpaceX plan “Sovereign Solutions”, an integrated service combining satellite broadband with secure data communications and sovereign network infrastructure. 4iG says that service is scheduled to launch in 2027 (4iG). The announcement does not specify who controls routing, encryption keys, data location, lawful-interception interfaces, incident response or the operational boundaries between 4iG, SpaceX and a government customer.

That is not a reason to dismiss the project. It is the correct diligence list. A resilient government link needs a defined trust model and failure procedure, not only a satellite beam. For carriers, the same principle applies to the commercial service: if the satellite path is presented as backup, the handover between terrestrial and non-terrestrial access must be measurable and operationally rehearsed.

Spectrum is the gating item in Europe

The timing of the announcement intersects with a change in the EU’s 2 GHz mobile-satellite framework. The European Commission proposed a new EU-level selection and authorisation procedure on 27 May 2026 because the current rights expire in May 2027. Its proposal covers the paired 1980–2010 MHz and 2170–2200 MHz bands and is intended to create consistent conditions for cross-border mobile-satellite services (European Commission; COM(2026) 311).

The proposal is not an authorisation for 4iG or SpaceX. It is a legislative process. National rights, technical coordination, market access, security review and compliance with the final EU framework still have to be resolved. The European Parliament’s legislative summary says the present model selected Inmarsat (now Viasat) and Solaris (now EchoStar) at EU level in 2009, while Member States granted the national rights of use; those rights expire in May 2027 (European Parliament).

For the Western Balkans, the problem is even less uniform. Albania, Montenegro and North Macedonia are not all in the EU, so an EU-level spectrum decision cannot by itself make the V2 service lawful in each country. 4iG will need a country-by-country path through spectrum administration, electronic-communications regulation, security requirements and, where relevant, coordination with incumbent mobile operators. That is why “global 2 GHz priority rights” should be treated as an input to authorisation, not as a substitute for it.

Resilience needs a terrestrial operating model

Satellite-to-phone connectivity is most useful when it is designed around the failure modes of the terrestrial network. Mountainous parts of the Balkans have genuine coverage gaps, and floods, power failures, fibre cuts or damaged mobile sites can isolate communities. A satellite overlay can provide a second access path, but it does not automatically provide a second core network, a second identity system or a second route to an internet exchange.

A carrier-grade design therefore needs explicit answers to five questions. Which traffic is allowed onto the satellite path? How are subscribers authenticated when the terrestrial core is unavailable? Where does the traffic break out, and under whose jurisdiction? What happens when a satellite cell is congested? And how is the service tested during a regional outage rather than only during a controlled demonstration?

The answers affect terrestrial investment. If the satellite service is limited to emergency messaging, it may complement fibre and mobile densification with relatively little substitution. If V2 eventually supports higher-rate data, operators may use it to extend public-service coverage, backhaul temporary sites or provide continuity to critical infrastructure. In either case, the satellite segment still depends on gateways, spectrum coordination, terrestrial interconnection and operations teams. The ground network does not disappear; its role changes.

What it means for Bulgaria and the region

For Bulgaria, the immediate lesson is not that satellite will replace Sofia’s fibre, IP transit or DWDM routes. It is that regional connectivity is becoming a portfolio of physical and regulatory paths. A Bulgarian carrier serving customers across Serbia, North Macedonia, Albania or Montenegro may increasingly be asked for a continuity design that combines terrestrial fibre, multiple upstreams, mobile access and satellite fallback.

That creates a practical opportunity for network operators, but not a reason for speculative capacity planning. The relevant products are integration and assurance: diverse terrestrial backhaul to mobile sites, protected transit, local peering, secure cloud access and clear failover tests. Sofia Connect’s market sits in the middle of that stack. Its value is not to imitate a satellite operator; it is to make the terrestrial paths, interconnection points and operational controls around new access technologies dependable.

The 4iG–SpaceX agreement is therefore an early regional signal, not a finished service. Before customers can treat Starlink Mobile as resilience, regulators must settle spectrum, operators must publish service boundaries, and the parties must show how satellite access behaves under real network failure. The satellite is the visible part. The difficult infrastructure is the system around it.
