Overview
- Reports tie full satellite voice support to Samsung’s Exynos Modem 5410, which is built to handle both non‑terrestrial networks and conventional 5G in one chip.
- Samsung confirms the modem complies with 3GPP Release 17, the standard underpinning modern satellite mobile services.
- The 5410 integrates LTE Direct‑to‑Cell for voice, NB‑IoT NTN for texts and location, and NR‑NTN for higher‑bandwidth use that could extend to video calling.
- Samsung states the modem uses a 4nm EUV process with lower standby power and supports peak download throughput up to 14.79Gbps.
- Inclusion across Galaxy S26 models remains unconfirmed, and any rollout of satellite calling would depend on operator partnerships, regional support, costs, and real‑world battery and thermal performance.
