Exynos 5410 supports 3GPP Release 17, the global standard for satellite mobile connectivity

Samsung is preparing a major leap in smartphone connectivity, with its upcoming Galaxy S26 lineup expected to support full satellite voice calling, moving beyond the emergency-only messaging currently available on most devices.
The development is linked to Samsung’s newly unveiled Exynos Modem 5410, a next-generation chip designed to handle both conventional cellular networks and satellite communication within a single modem. If implemented, the feature would allow users to make voice calls via satellite, even in areas without terrestrial network coverage.
At present, satellite features on smartphones — including Apple’s Emergency SOS — are largely limited to sending short text messages during emergencies. Samsung’s reported plans suggest a more ambitious approach, positioning the Galaxy S26 as one of the first flagship phones to offer broader satellite-based communication.

According to Samsung, the Exynos Modem 5410 supports 3GPP Release 17 standards, the global framework underpinning modern satellite and non-terrestrial mobile networks. This standard is increasingly being adopted by carriers and satellite operators worldwide to extend mobile coverage beyond traditional infrastructure.
Power efficiency has been a key challenge for satellite connectivity, which typically consumes more energy than standard cellular communication. Samsung claims the new modem is designed to minimise power consumption while maintaining stable satellite links — a critical factor if satellite calling is to be practical for everyday use.
Samsung has been investing in satellite-enabled technology for several years, but the Galaxy S26 could be the first device to bring these efforts together in a consumer-ready product. Reports suggest the company aims to offer satellite voice support from launch, rather than limiting the feature to emergency use.
If confirmed, the move would mark a significant shift in smartphone connectivity, potentially allowing users to stay connected whether in urban centres, remote regions, or areas affected by network outages.
