FYI - from what I can tell, newer Verizon Samsung phones have these pieces of functionality disabled out-of-the-box. However, I was able to successfully activate them on my S21 using instructions here:

I think it is fair to say, though, that neither Verizon nor Samsung either countenance or support doing this, and you probably do so at your own risk, possibly voiding some kind of protection or warranty offered by either in the process.
That said, it is a pretty simple procedure (at least on a Windows computer); just be sure to install the Samsung USB driver for Windows before you start.
