Your Galaxy S26 could make satellite calls, Samsung hints

By Paulo Vargas Published December 26, 2025

Samsung is laying groundwork for a potential jump in Galaxy S26 satellite connectivity, based on how it is describing the Exynos Modem 5410.

The company says the modem supports three different satellite network types, and it ties one of them to voice calling, which points to something more practical than a last resort satellite message.

With no official announcements just yet, it is speculated that the new modem will be used in the Galaxy S26 in select countries.

Samsung says the Exynos Modem 5410 integrates LTE DTC, NB IoT NTN, and NR NTN on a single chip, and it assigns each a different role.

LTE DTC, short for Long Term Evolution Direct to Cell, is the key promise. Samsung describes it as expanding capabilities by enabling voice calls, a clear step up from short emergency style messages.

NB IoT NTN, or NarrowBand Internet of Things Non Terrestrial Networks, is positioned for lighter tasks like location sharing and simple text transmission through satellites, including scenarios far from towers, even across deserts or oceans. Samsung says this portion is certified by Skylo.

NR NTN, short for New Radio Non Terrestrial Networks, is framed as the higher quality lane, with Samsung pointing to use cases like video calls.

If these capabilities land in the Galaxy S26 family, Galaxy S26 satellite connectivity starts to look like a layered fallback. Simple texts and location sharing sit at one end, voice calling becomes the big middle step, and higher quality communication sits at the top.

Samsung is also pitching this as a premium modem, not a niche add on. It says the chip is based on the 3GPP Release 17 standard, supports 5G NR dual connectivity across FR1 sub 6GHz and FR2 mmWave, and lists peak download throughput up to 14.79Gbps.

Efficiency and security get a nod, too. Samsung says the modem uses a 4nm EUV process for lower standby power consumption, and it highlights root of trust based hybrid PQC plus a security processor meant to protect sensitive Secure NV data such as IMEI.

The deciding details are still missing: which Galaxy models use the modem, whether satellite voice calling is enabled on day one, and where it is supported. Until Samsung spells that out, treat the Exynos Modem 5410 as capability, not confirmation.

If you care about off grid coverage, wait for a Galaxy S26 spec sheet that explicitly lists satellite calling, supported satellite modes, and regional availability.
