I would have suggested silent.link , while you can get a number not tied to your identity via esim, the main focus of numbers is a receiver for text and calls(also because it avoid people creating spam phone calls/txt). Which was originally for 2fa that only had cell # as an option. Also a number requires the user to be vigilant in paying their annual for it or they can lose the number. Also I think they can only cater for users in US, Canada and maybe UK.
It does also have third party repos such as sbopkg. This does a bunch of the movement for you when installing packages though you still need to manually install dependencies, BUT If you also add sboui which is a front end package resolution for dependencies then the process is much faster. I like the stability of Slackware, and also because its helps me get better for when I try the BSD since its very much like them as well.
