Samsung is currently rewriting the rules of European mobile infrastructure. Kyivstar has officially turned on Starlink Direct to Cell support for Samsung Galaxy users in Ukraine. This isn’t just a prototype or a limited beta; it’s the first commercial deployment in Europe that allows standard 4G LTE Samsung handsets to communicate directly with SpaceX’s low-Earth orbit (LEO) constellation without specialized hardware.
Key points
- Samsung 4G/5G users in Ukraine can now send SMS via Starlink satellites.
- The service is provided through Kyivstar and uses Starlink Direct to Cell tech.
- No special apps or extra hardware are needed; it works via standard SMS protocols.
- Users must enable “Automatic Network Selection” and have a clear view of the sky.
- Voice and data features are expected to be added to the satellite link in 2026.
How it Works: “Cell Towers in the Sky”
Unlike Apple’s proprietary SOS system, which requires a specific “pointing” gesture, the Kyivstar-SpaceX solution treats the satellite as a standard roaming partner.
- The Modem:The Starlink V2 Mini satellites are equipped with an onboardeNodeB modem. This allows them to act as a cellular mast in space.
- Device Support:Any Samsung device with3GPP Release 10(or newer) compatibility and a Kyivstar SIM can technically connect. This includes almost every Galaxy flagship from the S21 series through the unreleasedGalaxy S26 Ultra.
- The Handshake:When your phone loses terrestrial towers, it looks for the”Kyivstar | SpaceX”network ID. As long asAutomatic Network Selectionis enabled in your settings, the transition is seamless.
Current Limitations and 2026 Roadmap
Right now, the service is restricted to two-way SMS messaging. You won’t be scrolling Instagram via satellite just yet.
- The Environment:You must have aclear view of the sky. Heavy tree canopies or being indoors will still block the signal.
- The Speed:Bandwidth is extremely limited. We are looking at “kilobits per second” territory, which is why text is the priority.
- Voice & Data:Kyivstar and Samsung have confirmed thatVoice over LTE (VoLTE)and basic data for IoT devices are scheduled for a broader rollout later in2026.
Deployment Zones and Security
The service is live across the majority of Ukraine, serving as a critical backup for a country dealing with damaged terrestrial infrastructure. However, there are geofenced dead zones. Due to regulatory and security requirements, satellite messaging is disabled in temporarily occupied areas, active combat zones, and a 20-50km buffer strip along the border to prevent interference with neighboring nations’ spectrum.
