CNET - One of the biggest complaints of smartwatches is that they're really just dependent accessories to your phone. They need a phone to work.
Not all of them, though. The Samsung Gear S2 3G is a smartwatch that has its own cell service. It can work without any phone at all. I wore the Gear S2 3G for a few weeks. And, now I've taken it off. It's an amazing little demonstration that a watch can be its own phone...but I can't see enough reasons for most people to buy this.
