Samsung recently officially unveiled the Exynos 2600, the world’s first mobile processor manufactured using 2 nm technology. This chip is expected to appear in the Galaxy Z Flip8 and Galaxy S26 smartphones in at least one country. When the processor was announced, the Korean manufacturer kept quiet about its next-generation mobile modem, but now information about it has surfaced.
The most notable feature is satellite communications, which combines LTE Direct-to-Cell, NB-IoT NTN, and NR-NTN on a single chip. This enables voice calls, text messages, location sharing, and even video calls in areas without terrestrial network coverage.
In addition to speed and coverage, Samsung placed a strong emphasis on security. The modem supports hybrid post-quantum cryptography, protecting sensitive data, such as device identifiers, from future quantum-based threats. Separating the modem from the main processor also allows Samsung to manage heat more efficiently.
There’s no official confirmation yet that the Samsung Exynos 5410 will appear in the Galaxy S26 series, but it’s positioned as the Korean manufacturer’s most advanced modem. It’s manufactured using EUV lithography and a 4 nm process technology. It’s based on the 3GPP Release 17 standard, offering dual 5G NR connectivity in the sub-6GHz and mmWave bands, and claimed downlink speeds of up to 14.79 Gbps.
