Rumors are swirling that Samsung's next flagship could finally bring true satellite voice calling to the Galaxy S26 family — and the likely trigger might be a new Exynos modem inside the phone. While nothing is confirmed, chips and modem details leaked around the Exynos 2600 point to a hardware path for satellite connectivity.
Why the Exynos Modem 5410 could matter
When Samsung revealed the Exynos 2600 — its first 2nm chip — the company stayed curiously quiet about the modem pairing. New information suggests an Exynos Modem 5410 could be bundled with the platform, and that modem looks engineered for non-terrestrial networks.
The Modem 5410 reportedly integrates three key radio stacks on a single package: NB-IoT NTN, LTE DTC and NR NTN. Each brings different strengths. NB-IoT NTN (NarrowBand IoT for Non-Terrestrial Networks) is designed for tiny, extremely reliable data bursts — think location pings or short text telemetry that can work across deserts or open ocean. Samsung claims Skylo certification for that slice, which adds credibility for global IoT reach.
LTE DTC (Long Term Evolution Direct to Cell) is the most intriguing piece for consumers: it opens the door to extended satellite-based services, including voice calls. NR NTN (New Radio Non-Terrestrial Networks) targets higher throughput and could, in time, support richer services like satellite video calls or faster data fallback when terrestrial networks fail.
On paper the modem looks premium: built on a 4nm EUV process, aligned with 3GPP Release 17, and supporting 5G NR dual connectivity across FR1 (sub-6GHz) and FR2 (mmWave). Peak download speeds cited for the platform reach up to 14.79 Gbps — impressive, even if real-world speeds will vary dramatically when using satellite links.
That said, we don’t have official confirmation that the Exynos Modem 5410 will appear in every Galaxy S26 model — or in all regions. Samsung has used multiple chip partners and regional variants in the past, so availability could be staggered.
Bottom line: if Samsung does bring advanced satellite connectivity to the S26 series, the Exynos Modem 5410 is the most likely enabler. Keep an eye on chipset announcements and regional model specs as Samsung prepares its next flagship launch.
