There was speculation that Samsung could use smartphone-to-satellite technology in its Galaxy S23 much like Apple has for the iPhone 14, but that didn't happen in the end. Now, the company has unveiled a new standardized 5G NTN (non-terrestrial network) modem that will enable two-way communication between smartphones and satellites. The technology will allow users to send and receive calls, text messages and data without the need for a cellular network, and will be integrated into Samsung's future Exynos chips.
