Sharing an internet connection allows multiple devices to access the same network, making it possible to stay connected when public Wi-Fi or cellular data is unreliable. Most major operating systems support internet sharing, including iOS, Android, Windows, and macOS, allowing users to share their cellular or wired connections over Wi-Fi, Bluetooth, or USB. With a few simple steps, users can enable personal hotspots on their devices, set up mobile hotspot plans or pocket Wi-Fi devices, and share their internet connection with others, making it easier to work remotely or stay connected in public areas.
