The Apple watch works because it's one company coordinating everything for a huge market. Apple can make agreements with carriers that other company (smaller ones, especially) can't.
The Apple watch uses an eSIM. You need a cell plan to use it as a cell phone.
The watch is a cellphone. (Mapping a phone number to two devices is trivial: It's a database lookup.)

Again, the issue isn't technology, It's being able to make money.
You’re not paying attention and you are not understanding. Any Apple Watch, not just cell enabled ones, can make calls. Cell service is just one of the ways they do it.
