Samsung Galaxy S26 series could be getting satellite voice calls | Infinium-tech

Before you get too excited, nothing has been confirmed yet. We recently learned about the Samsung Exynos 2600 chip – the first chip built on the 2nm process. The chip is rumored to power the upcoming Galaxy Z Flip8 and potentially the S26 family in at least one country. When the Exynos 2600 was unveiled, Samsung was suspiciously quiet about its modem. Now details have started to emerge about the Exynos Modem 5410, which may be part of the Exynos 2600 package.

The Exynos Modem 5410 integrates LTE DTC, NB IoT NTN, and NR NTN on a single chip. NB IoT NTN, or Narrowband Internet of Things Non-Terrestrial Network, is at the low end of the communications spectrum. This allows very sparse data throughput, such as location data or text transmission, but does so reliably even across deserts or oceans. Samsung says this part is certified by Skylo.

LTE DTC, short for Long Term Evolution Direct to Sale, is arguably the highlight here as it promises expanded satellite communications capabilities like voice. And last but not least, there’s NR NTN, short for New Radio Non-Terrestrial Network, which promises better data throughput and could enable things like satellite video calls in the future.

Again, we don’t have any confirmation yet that the Exynos modem 5410 is coming to the Galaxy S26 series, but we do know that it is positioned as one of the company’s most premium modems, built on the advanced 4nm EUV process. It is based on the 3GPP Release 17 standard, supports 5G NR dual connectivity in FR1 sub 6GHz and FR2 mmWave, and lists peak download throughput up to 14.79Gbps.

Bottom line: If the Galaxy S26 family comes with advanced satellite connectivity, we know the first place to start looking for potential details is probably the Exynos modem 5410.
