Why would you want a watch that's connected to a cellular network?
I have a bluetooth watch, and it wouldn't benefit in any way by being able to walk alone. My phone is never more than a room away. Plus, it's useless by itself. I can't type on it, because the screen is too small. I can't use the internet, due to the same issue. I can't call on it, because it would be too impractical, and would likely require a headphone jack, so I can hear whoever is calling.
By then, it wouldn't even be a smartwatch, it would just be a shitty phone on your wrist.
