Samsung has quietly revealed a new mobile modem that could change how its next flagship smartphones stay connected.
The South Korean technology company has unveiled the Exynos Modem 5410, a dedicated 5G chip that is expected to power select Galaxy S26 models along with the Exynos 2600 processor. Although the Galaxy S26 series is still a few months away from launch, the modem listing on Samsung’s website points to major improvements in satellite connectivity.
The Exynos Modem 5410 combines satellite and cellular communication in a single chip. It supports LTE Direct to Cell technology, along with NB IoT NTN and NR NTN satellite standards based on 3GPP Release 17. According to Samsung, LTE Direct to Cell allows voice calls through satellites, while NB IoT NTN enables location sharing and text messaging using satellites positioned high above the earth. This could allow users to communicate even in remote areas such as deserts or no signal zones.
The modem also supports NR NTN, which enables higher quality satellite communication, including video calls. This suggests that the Galaxy S26 lineup could offer voice and video calling via satellite, a first for Samsung smartphones.
Samsung notes that the new modem delivers more reliable and secure communication through support for Root of Trust based Hybrid PQC and improved low power consumption. The previous Exynos Modem 5400 only offered early satellite features, making the new model a significant step forward.
With the Exynos Modem 5410, the Galaxy S26 family is expected to offer enhanced satellite calling features along with potential battery efficiency gains. This would be a clear upgrade over the Galaxy S25 series, which supported only basic emergency text messaging via satellite. Similar satellite features are already present on smartphones from other major brands.
The Galaxy S26 series is expected to launch in February and may include the Galaxy S26, Galaxy S26 Plus, and Galaxy S26 Ultra. Select markets could receive models powered by a Galaxy branded version of the Snapdragon 8 Elite Gen 5 chipset, while regions such as South Korea and Europe may get variants equipped with the Exynos 2600 processor.
