Apple Watch Series 7 GPS + Cellular is the next generation smartwatch that promises to enhance the user experience. The most durable Apple Watch to date has been updated to be even better. An IP6X dustproof rating and 50% more impact-resistant glass than older models help protect the Retina display that's always on. The size of the wristwatch screen has been increased by almost 20% by reducing the size of the edges of the watch. An all-day battery life and 33% faster battery charging time compared to the previous version ensure that your watch is always ready for use. Plus, comprehensive health features such as blood oxygen monitoring and ECG will help you get to know your body even better. The Cellular model comes with mobile connectivity (wireless carrier contract required), so you can go out with just the watch on your wrist and your phone at home. With a cellular-connected Apple Watch Series 7 GPS + Cellular with an active mobile connection, you can make calls and send messages - all without your iPhone. You can even make an emergency call while traveling abroad with just a press of the side button. When Apple Watch is away from iPhone and connected to the mobile network, you can receive calls and messages from your active connection. If your iPhone is powered on, you can receive messages and notifications about incoming calls to another connection even when your iPhone is not nearby. If you answer a call, your watch automatically calls back using the active connection. Cellular models are optimized for use in the country where they were purchased, and not all models will work in all countries or regions.
