Samsung has quietly upgraded the satellite game for its next flagship. The new Exynos Modem 5410 delivers faster 5G, wider network support and — crucially — expanded satellite connectivity that could enable voice and video calls from areas without cellular coverage.
What the Exynos Modem 5410 actually is
The Exynos Modem 5410 is Samsung's latest standalone 5G modem, built on a 4nm FinFET process. It supports both mmWave and sub-6GHz 5G bands, along with legacy 2G, 3G and 4G networks. Peak download throughput reaches up to 14.79 Gbps, a substantial jump for modem performance and power efficiency over the prior generation.
Satellite connectivity that's more than messaging
Where the 5410 stands out is its expanded satellite support. It works with three satellite communication standards:
- LTE DTC
- NB-IoT NTN
- NR-NTN
Previous Exynos modems supported NB-IoT and NR-NTN only. Adding LTE DTC opens new possibilities: devices with this modem can handle voice and video calls, location sharing and richer messaging directly over satellite links, without relying on a terrestrial cellular tower.
Security, encryption and trusted boot
Security was clearly a focus. The 5410 includes a ROM based Root of Trust and a Hybrid Post-Quantum Cryptography approach for long-term resilience. A dedicated Security Processor can encrypt sensitive identifiers such as IMEI numbers, improving device authentication and protecting user data over both terrestrial and satellite paths.
Pairing with the Exynos 2600 and handset plans
Samsung's Exynos 2600, the company's new 2nm application processor, does not include an integrated modem. That means it will be paired with an external modem like the 5410. Samsung is expected to combine the Exynos 2600 and Exynos Modem 5410 in the Galaxy S26 and Galaxy S26+ for selected markets, giving those models enhanced 5G speed and broader satellite functionality.
Why this matters now
Imagine being off-grid and still able to place a video call or share precise location coordinates — that is the practical promise here. For journalists, first responders and travelers in remote regions, integrated satellite calling could be a genuine safety feature. Real-world availability will still depend on carrier partnerships, satellite service coverage and regional regulations, but the technical groundwork is now in place.
For readers tracking the smartphone race, Samsung's new modem signals a shift: modem and satellite capabilities are becoming central to flagship feature sets, not niche extras. Expect carriers and manufacturers to test and expand satellite services over the coming year.
