Built-in SIM Stay connected even without your phone.
The Apple Watch Series 3 Cellular has an electronic SIM built-in so you can make and receive calls, send texts, and see app notifications.
It's ultra-convenient for those times you don't want to carry your iPhone - going for a jog, heading to the beach, or simply running a quick errand.
Stream music right from your wrist.
Simply ask Siri what you want to play and find the best rhythm for your workout or commute.
Ask Siri In addition to being able to ask Siri to set reminders, send an invitation, or give you directions, Siri now talks back, so you can get the info you need without having the check your screen - great for directions on the go, or quickly checking the weather forecast.
