Apple unveiled the Apple Watch Series 3 on Tuesday.
It's the latest Apple Watch, and its big new feature is that it adds cellular connectivity, which allows users to send messages and receive phone calls even when an iPhone isn't nearby. The number is the same number that you use on an iPhone, Apple said. You can also stream music.
