Yeah for sure! So you sort of need a phone paired with it, but only as in you need a family member (or someone on your phone plan) to have an iPhone, but the watch owner themselves doesn't actually need any other phone that the watch.

It's called "Family Setup": https://support.apple.com/en-us/109036, and it lets me use the watch in what is sometimes called "Standalone mode" or "Companion mode" in different apps.

If you go down this route, know that many apps in the app store will not be downloadable, as they don't support "Companion mode", but I can still get everything I personally needed just fine.

As far as the SIM goes, I think I'm using an electronic sim card? I'm not positive
