End of No-Signal Areas? Galaxy S26 Is Expected to Debut Advanced Satellite Connectivity

Samsung is taking a major step toward eliminating mobile dead zones. Following the announcement of the Exynos 2600, the chipset expected to power the Galaxy S26 and Galaxy S26 Plus, the company has officially unveiled the Exynos 5410, a standalone modem designed to redefine smartphone connectivity.

This move suggests that satellite communication will no longer be exclusive to Ultra models, potentially reaching a broader range of Galaxy S26 devices.

Exynos 5410: A Dedicated Modem for Next-Gen Galaxy Phones

Unlike previous generations, the Exynos 2600 does not feature an integrated modem. Instead, Samsung opted for a dedicated connectivity solution, similar to Apple’s recent hardware strategy.

Manufactured using a 4 nm EUV process, the Exynos 5410 supports 3GPP Release 17 and delivers download speeds of up to 14.79 Gbps through combined sub-6GHz and mmWave networks.

Built-In Satellite Connectivity

The most notable feature of the Exynos 5410 is its native satellite support, integrating multiple standards into a single chip:

• LTE Direct-to-Cell
• NB-IoT NTN
• NR-NTN

This enables:

• Voice calls
• Text messaging
• Location sharing
• Even video communication

All of this works without any terrestrial mobile network coverage, making the Galaxy S26 lineup far more reliable in remote areas.

As a result, satellite connectivity is expected not only on the Galaxy S26 Ultra, powered by the Snapdragon 8 Elite Gen 5, but also on other models in the series.

Post-Quantum Security Built In

Samsung also placed a strong emphasis on security. The Exynos 5410 supports Hybrid Post-Quantum Cryptography (PQC), ensuring long-term protection against future threats posed by quantum computing.

This makes the modem one of the most future-proof connectivity solutions in the smartphone market.

Improved Thermal Management and Efficiency

Separating the modem from the main chipset allows Samsung to:

• Improve heat dissipation
• Optimize power consumption
• Allocate more space for CPU, NPU, and GPU components

The Exynos 2600, Samsung’s first 2 nm chipset, also introduces a new AMD RDNA 4-based GPU, promising significant gains in graphics performance.
