A mobile hotspot is a portable device or feature on a smartphone that provides internet access to other devices using cellular data. It allows users to connect laptops, tablets, or other smartphones to the internet when Wi-Fi is not available. This is especially useful for people on the go or in areas with limited connectivity. To use a mobile hotspot, you typically enable the feature in your device's settings, which creates a secure Wi-Fi network. Other devices can then connect to this network, similar to how they would connect to a regular Wi-Fi router. Mobile hotspots are convenient for travel, work, or outdoor activities.
