Cellular-Enabled Apple Watch
You can now connect directly to the internet with the new cellular-enabled Apple Watch Series 3. That means you can stream music, get notifications, and make calls without being tethered to your phone. If you have an Apple Music subscription, you have access to its library of 40 million songs without being connected to your iPhone, instead of having to create a
watch playlist like with older models.
To support these exciting new functionalities, Apple built an electronic SIM card that fits inside the watches' form factor and uses the display as the antennae. Apple also added a dual-core processor that's up to 70 percent faster than previous models and a W2 chip for better battery performance. Overall, you'll experience much less lag time when using your new watch. Siri can also respond to you now, instead of just displaying answers on your screen.
I have found the Apple Watch to be the best of all the fitness trackers I've tried. By adding a cellular connection, it expands the feature set of the device enough to make it no longer just a great fitness band but also a wearable that can accomplish much of what we've previously relied solely on smartphones for. However, if you're mainly interested in fitness tracking, Apple offers a non-cellular version of the Series 3 that has the W2 chip, so you can expect better battery performance for your workouts (see pg. 38 for our Apple Watch buyer's guide to find the right model for you).
The cellular model will add about $5–$10/month to your existing phone carrier fee, and your watch will use the same number as your phone (thankfully). Overall, the Apple Watch Series 3 is great for people who hate being tethered to their phones but rely on the practicality of being reachable.
One of the most exciting things about the Apple Watch that Apple highlighted during its event is its potential to save lives. Apple played a commercial sharing stories of how Apple Watch users discovered serious health issues like diabetes or heart arrhythmia or called for help in a car crash. Adding a cellular connection makes the potential of the watch even greater as a safety device, whether as a way for people to call 911 in cases of domestic abuse or for elderly people who want to safely continue to live independent lives.
