Verizon, AT&T, and prepaid carriers in the country are likely to follow suit in the coming days. Or weeks, at worst.

Meaning that as things stand right now, the Galaxy S9 series is only guaranteed two more security patches. Or half a year's worth of updates, if you like. But getting four full years out of a smartphone sounds like a good deal in this day and age. Afterward, you might want to consider upgrading. A Galaxy S9-series smartphone was a suspect purchase even last year.
As for the August 1st, 2021 security patch level, this update already made its way to the unlocked variants of the Galaxy S9 and Galaxy S9+ in the U.S. It started to, at least, about a week ago. If you still haven't received your download, try going to Settings > Software update > Download and install. Or turn to our firmware archives and do things the good ol' manual way.
