Satellite messaging via Starlink is poised to transform the way we communicate. in areas where conventional networks do not reach. This technology, already making headlines for its trials around the world, promises to connect isolated locations, rural areas, or disaster-stricken regions where mobile connectivity has always been a challenge.
Ukraine will be a pioneer in Europe in deploying mobile messaging via Starlink.Users of the leading operator Kyivstar will be able to send and receive messages, as well as access voice and data services later, directly from their smartphones without the need for additional equipment.
Launch and key partners in the deployment of Starlink messaging
According to Oleksandr Komarov, CEO of Kyivstar, The first phase of this technology will arrive by the end of 2025, and will focus on messaging services using OTT platforms such as WhatsApp or Signal. In the next phase, planned for the second quarter of 2026, voice services and mobile broadband connection via satelliteThis will be possible thanks to "Direct to Cell" technology, which allows smartphones to connect directly to the Starlink satellite network in orbit.
The agreement between Kyivstar and SpaceX, signed at the end of 2024, has allowed field trials to begin in Ukraine. This collaboration not only strengthens the country's communications during wartime, but also positions Ukraine at the forefront of mobile satellite connectivity in Europe.
Starlink technology is backed by a constellation of more than 7.000 satellites, far above other similar initiatives such as OneWeb. This massive deployment is key to ensuring a wide and reliable coverage, regardless of geographic location or available ground infrastructure.
Compatibility and operation of satellite messaging on smartphones
One of the strong points of the system is that does not require special devices or external antennasConventional LTE-enabled smartphones will be able to automatically connect to the Starlink network when they detect a lack of terrestrial coverage. This is made possible by satellites equipped with eNodeB modems, capable of acting as mobile towers in space.
During the initial phase, the connection speed for messaging and calls will be similar to that of a 2G/3G network, but a higher speed is expected. gradual evolution towards LTE speeds basic (between 1 and 20 Mbps) in areas with better satellite coverage. The system is compatible with a wide variety of devices, including recent models from Apple (iPhone 14, 15, and 16), Samsung Galaxy, Google Pixel, and Motorola, as long as they have the latest software version installed.
The extra latency, between 30 and 100 milliseconds compared to a terrestrial tower, it is not an issue for basic messaging and calls, and coverage can reach remote areas, offshore or mountainous regions, as long as there is direct visibility to the sky.
Benefits, challenges, and international expansion of the Direct to Cell service
The deployment of Starlink messaging goes hand in hand with improvements in the resilience of local telecommunications infrastructureFor example, Kyivstar's network is already capable of operating for up to 10 hours during power outages, a particularly relevant feature in conflict contexts like the one in Ukraine.
In other regions, the satellite system has already proven its worth. New Zealand, with its operator One NZ, has exceeded two million messages sent through the Starlink network, acting as a key solution for rural communities and areas affected by natural disasters. The United States is also leading the way, with T-Mobile, Verizon, and AT&T participating in initial testing and deployments of the service. Basic features include text messaging, geolocation, and emergency calls, with plans to expand to voice and data transmissions in future updates.
The business model is still in the fine-tuning phase, with some operators offering the service free of charge in pilot tests and others offering flexible plans for different user profiles. The arrival of Direct to Cell does not mean replacing the terrestrial network, but rather to complement it, especially in emergencies and in areas where the expansion of the infrastructure would be economically unviable.
Current terms of use and limitations
In order to use this technology, the requirements are have a compatible smartphone, have the most up-to-date software installed, and be in an area covered by the satellite constellationInitially, services will be limited to simple messaging and emergency calls, with plans to expand functionality as the network and agreements evolve.
Moving toward fully integrating voice calls and internet access from space poses technical challenges, such as managing interference and congestion in high-demand situations, but testing so far has been promising.
Globally, the list of countries and operators partnering with SpaceX is growing. In addition to Kyivstar in Ukraine and One NZ in New Zealand, notable collaborations include T-Mobile in the United States, Salt in Switzerland, Entel in Peru, and KDDI in Japan. The roadmap includes a progressive expansion to other markets, boosting universal connectivity and closing the digital divide in communities historically overlooked by large telecommunications networks.
Messaging via Starlink Direct to Cell represents one of the most significant changes in the sector in recent years, opening a new horizon for mobile communication, both in everyday situations and in critical scenarios where every message can make a difference.
