How to use your phone or another device as a hotspot
Most smartphones and tablets with an active data plan from a carrier can work as mobile hotspots. A mobile hotspot provides a secure internet connection for other devices through WiFi, Bluetooth, or a USB cable.
Every device you connect, or tether, uses data from your plan. Check your data plan, not all service providers allow you to use your phone as a hotspot, and for those that do, you must know how mobile hotspot use impacts your data plan.
