Video showing an AT&T Samsung Galaxy S21 Ultra (model SM-G998U) that is out of date on firmware, and will not update over wifi due to AT&T's strict update requirements. For their Android devices to update their software over wifi, AT&T requires that an active AT&T SIM card be inserted. If not, even if the device's software is out of data, it will say "Software is up to date" when you try checking for an update.

There are hundreds of websites that offer downloads for Samsung firmware, for manually updating via a computer. But it's almost impossible to find AT&T firmware on these sites because in addition to the OTA update requirements, AT&T also prohibits their software from being available publicly on websites like that. But our business has an inside source that has provided us with access to a Samsung tool that allows us to download the software for updating any AT&T Samsung Galaxy device manually, using a computer. (And this actually also applies to Cricket also: we can get software for any Cricket Samsung device as well.)
