The promise to end the areas without mobile coverage It's getting closer to becoming commonplace. Starlink, SpaceX's satellite connectivity project, has begun activating its direct satellite-to-mobile phone connection service, a move that aims to keep users connected even where traditional mobile networks don't reach.
This new service, named as Direct to CellIt eliminates the need for satellite dishes and additional equipment: all you need is a compatible smartphone and clear skies to connect to the company's constellation of low-Earth orbit satellites. This move could profoundly alter the telecommunications market, starting in Latin America and with an eye toward expansion into Europe.
Unlike Starlink's domestic service, which requires the installation of the well-known "dish" or satellite dish, Direct to Cell turns your mobile phone into a satellite signal receiverSpaceX's low-Earth orbit satellites incorporate an eNodeB modem, the same type of technology used by 4G mobile phone towers on the ground.
Thanks to this design, the satellites act as floating cell phone antennas at an altitude of approximately 550 kilometers. When the phone loses signal from regular terrestrial networks (on an isolated road, in rural areas, or even at sea), the device can search for the LTE carrier broadcast by the nearest Starlink satellite and establish a connection automatically.
The entire process is transparent to the user: the mobile behaves as if it were doing roaming over a conventional networkwithout needing to install apps, configure special settings, or change the SIM card. Starlink's goal is for it to feel like a natural extension of the user's usual coverage.
In this first phase, the Direct to Cell network focuses on the low data demand messaging services (SMS and apps like WhatsApp or similar). Starting in 2025 and 2026, Starlink plans to gradually add more intensive data traffic and voice calls, which would open the door to web browsing, IoT services, and much broader everyday mobile use.

Technical advantages: low latency and use of standard LTE
One of the strengths of this proposal is that It relies on the existing LTE (4G) standardThis allows the existing smartphone ecosystem to be reused without the need to launch dedicated phones. Any modern 4G device can, in theory, communicate with Starlink satellites.
Furthermore, by operating in low Earth orbit, the Starlink constellation offers much shorter response times than classic geostationary systems. While other satellite solutions can have latency exceeding 600 milliseconds, Starlink's broadband service measurements hover around 45 milliseconds, a significant difference for video calls, real-time messaging, or interactive applications.
This combination of reduced latency and standard LTE protocol puts Starlink in an advantageous position to compete against both traditional satellite providers and the companies themselves. mobile networks in areas where infrastructure is not cost-effectiveIn practice, the service aims to become a complement that fills the gaps in terrestrial coverage, rather than a complete replacement.
The key to this strategy also lies in the use of authorized radio spectrumThis allows satellites to transmit directly to mobile devices without always passing through large intermediate ground stations. This reduces complexity and provides more flexibility for a more stable experience in challenging environments.
Latin America as a laboratory: the role of Chile and Peru
The commercial rollout of Direct to Cell has begun in Latin America, with Chile as a pioneering countryThere, the operator Entel has become a key partner to test the integration of the satellite network with existing mobile services, offering data packages aimed at users in rural areas, mountainous areas or regions with poor coverage.
The initial plans, which include consumption periods of 150 GB and 450 GB monthlyThese systems are primarily designed as a connectivity solution in areas where extending fiber optic cables, radio links, or deploying new towers is expensive or simply not feasible. They are not just an emergency measure: the focus is on their everyday use by households, businesses, and workers who live in or commute through these areas.
Peru has also joined the project through similar agreements, which allows Starlink validate their technology in varied geographical environmentsFrom mountain ranges to jungles or coastal areas. These trials in neighboring countries constitute a testing ground for expanding the service to the rest of the region and, in the medium term, to other markets.
The alliance with local mobile operators It is fundamental: Direct to Cell is not marketed, at least for now, as an independent service for the end user, but as a feature that the telecoms themselves integrate into their plans, either included in premium rates or as an extra monthly payment.
Technical requirements: what the mobile phone and the user need
To take advantage of Direct to Cell, the user does not have to buy a new device, but does have to meet several requirements. basic compatibility requirementsThe first is that the phone has 4G/LTE connectivity, a standard present in the vast majority of smartphones in circulation in recent years.
The software aspect also comes into play: Starlink and the operators recommend having Android 12 or later in the case of Android, and iOS 16 or higher in the Apple ecosystemHaving the operating system updated helps the device correctly recognize the satellite network as if it were another terrestrial cell within the operator's coverage map.
The third element is the physical environment. The service is designed to function in outdoor areas with direct visibility of the skyTall buildings, nearby mountains, or metal structures can interfere with the satellite connection. Therefore, while it can be helpful in emergencies, its best performance is in open areas, fields, roads, or maritime environments.
In addition to these technical requirements, there is a determining factor: the need for the user to be a customer of an operator with an agreement signed with StarlinkWithout that agreement, the mobile phone will have no way to authenticate itself on the satellite network, even if it meets all the hardware and software requirements.
The role of operators: business models and projected tariffs
In countries where trials are already underway, Direct to Cell is being considered as a value-added service linked to mobile plansThe information coming from Latin America and other markets allows us to outline two main marketing schemes.
On the one hand, some companies are considering including satellite connectivity in Premium plans at no extra costThis is offered as a competitive advantage for high-end customers. In this case, the user would see their coverage expanded without having to modify their bill, but it would be limited to the most expensive plans.
On the other hand, the option of offering Direct to Cell as a monthly payment supplementThis would be added to any existing plan for an extra fee. International references point to an approximate figure of $10 per month, using markets like the United States and agreements with carriers like T-Mobile as examples.
In both models, the concept is that the service does not replace the normal mobile network, but rather that expand into areas where land infrastructure does not reachIn standard coverage, the phone would continue to use the usual antennas; only when the signal disappears would the Starlink satellite link come into play.
From a regulatory perspective, different countries will need to define how this type of hybrid connectivity fits in, especially with regard to the use of mobile spectrum. interoperability between networks and universal service obligations in rural or remote areas.
Potential impact in Spain and Europe: what could change
Although the initial trials are focused on Latin America, Starlink Direct to Cell technology has a clear potential fit in Europe and, in particular, in SpainThe country has an extensive road network, rural areas in the so-called "Empty Spain" and large maritime areas where mobile coverage remains patchy.
For sparsely populated areas, deploying new cell towers may not be profitable for operators, leaving many towns and regions with very limited signal. A direct satellite connection service could act as a solution. complement to existing 4G and 5G networksguaranteeing basic connectivity in those coverage gaps.
At the European level, the arrival of solutions of this type would intersect with other public and private initiatives aimed at universal coverageThis includes satellite networks promoted by the European Union. This means that any Starlink launch in the mobile sector in the region will have to comply with regulations on competition, communications security, and radio spectrum management.
In Spain, factors such as coordination with the main operators (Movistar, Orange, Vodafone, MásMóvil, etc.), which have already invested significantly in fiber and 5G, also come into play. The most likely option would involve agreements in which Starlink is integrated as a coverage reinforcement in rural areasinstead of trying to replace the infrastructure already deployed.
Practical uses: from emergencies to everyday life
Beyond the technological interest, the usefulness of Direct to Cell will be measured by its ability to solve real connectivity problemsIn emergency situations, traffic accidents on roads without coverage, mountain excursions or sea crossings, being able to send a message or make a basic call can make all the difference.
But Starlink's ambition goes beyond specific situations. The company envisions this system as a tool Suitable for everyday use in rural areasallowing small businesses, farms, itinerant professionals or public services to have a minimum communication channel without being completely dependent on the availability of nearby antennas.
As the data and voice phases are activated, the door also opens to integrating devices from Internet of Things (IoT)Remote sensors, environmental monitoring systems, or industrial equipment in remote locations, all using the same satellite infrastructure that serves mobile phones.
The final user experience will depend, however, on how each operator limits or prioritizes traffic. It is expected that, at least in the initial stages, speed and data volume restrictions are imposed to ensure the stability of the satellite network and avoid saturations.
By combining a massive constellation of low-Earth orbit satellites, agreements with major telecoms, and the use of established mobile standards, Starlink Direct to Cell aims to become a a relevant piece within the map of global connectivityIf the planned deployments are completed and regulators do not put a stop to it, the coming years could bring a real reduction in coverage "dead zones," both in Latin America and Europe, with a direct impact on how we use mobile phones when we leave urban centers.
