Total Wireless Hotspot is a feature that allows you to turn your mobile device into a portable WiFi hotspot. It works by utilizing your phone's data plan to provide internet access to other devices, such as laptops, tablets, or other phones. Once you activate the hotspot feature, your phone creates its own WiFi network. You can then connect other devices to this network, just like you would connect to any other WiFi network. The data used by the connected devices is then deducted from your phone's data plan.
