Samsung may still be a few months away from unveiling the Galaxy S26 series, but the company has already hinted at a major connectivity upgrade. The South Korean tech giant has quietly introduced the Exynos Modem 5410, a next-generation 5G modem expected to power select Galaxy S26 models alongside the upcoming Exynos 2600 chipset.

The newly announced modem brings full satellite communication support, marking a significant step forward compared to previous Galaxy smartphones.

Exynos 5410 Brings Voice and Video Calls via Satellite

According to details listed on Samsung’s official website, the Exynos Modem 5410 integrates both cellular and satellite connectivity into a single chip. It supports multiple satellite communication standards, including LTE Direct-to-Cell (DTC), NB-IoT NTN, and NR-NTN, all based on 3GPP Release 17 specifications.

Samsung highlights that LTE DTC technology enables voice calls via satellite, allowing users to stay connected even in areas with no mobile network coverage. Meanwhile, NB-IoT NTN enables essential features such as text messaging and location sharing through satellites positioned high above the Earth. For more data-intensive tasks, NR-NTN support could make satellite-based video calls possible, offering a much richer communication experience.

This means Galaxy S26 users could potentially make calls, send messages, or share their location from remote regions like deserts, mountains, or rural zones without cellular signals.

Improved Security and Power Efficiency

Samsung claims the Exynos 5410 also delivers enhanced security and reliability, thanks to Root of Trust–based Hybrid Post-Quantum Cryptography (PQC) support. Additionally, the modem is designed for lower power consumption, which could translate into better battery life when using satellite features.

This is a notable upgrade over Samsung’s earlier Exynos Modem 5400, which only offered limited satellite capabilities.

Galaxy S26 vs Galaxy S25: A Major Connectivity Leap

The Galaxy S25 lineup provided basic emergency satellite texting, similar to early implementations seen on rival devices. However, with the Exynos 5410, the Galaxy S26 family could offer true satellite calling and richer communication features, bringing Samsung closer to competitors like Apple and Google, which already support satellite-based emergency services.

Galaxy S26 Launch Timeline and Chipset Strategy

Reports suggest the Samsung Galaxy S26 series may launch in February 2026, featuring the Galaxy S26, Galaxy S26+, and Galaxy S26 Ultra. Samsung is expected to continue its dual-chip strategy, with Exynos 2600–powered variants likely arriving in markets such as South Korea and Europe, while select regions may receive models running a Galaxy-optimized Snapdragon 8 Elite Gen 5 chipset.

If these reports hold true, the Galaxy S26 series could mark Samsung’s first major leap into full satellite connectivity, positioning it as a serious contender in next-generation mobile communication.
