A mobile hotspot is a portable device that provides internet access to other devices, such as smartphones, tablets, and laptops. It connects to a cellular network and shares that connection via Wi-Fi, allowing multiple users to access the internet on the go. Mobile hotspots are especially useful in areas without reliable Wi-Fi, such as during travel or outdoor activities. Many smartphones also have a built-in mobile hotspot feature, enabling users to share their cellular data connection. Users can typically manage their hotspot settings, including security options and data limits, to ensure a safe and efficient internet experience while using their mobile devices.
