Yes, the Apple Watch Series 7 can function independently without an iPhone for various tasks, especially if it is the LTE model. With LTE connectivity, the watch can make calls, send texts, and access the internet directly without needing to be connected to an iPhone. This allows users to leave their phone behind during activities like running or swimming and still remain reachable and connected.
However, for initial setup, software updates, and some specific applications and features, the Apple Watch Series 7 still requires pairing with an iPhone. This includes the setup process, syncing of certain data, and installation of apps. Therefore, while the watch offers substantial independence for daily tasks and connectivity, it still relies on an iPhone for broader functionality and management.
