Ever been stuck in a situation where you need to get a computer or tablet online with no Wi-Fi nearby? If you have an iPhone with a 3G or 4G data connection or better, that problem can be easily solved with a Personal Hotspot.
Instructions in this article apply to iOS 12, although functionality is similar for recent versions of the Apple mobile operating system.
Personal Hotspot Explained
Personal Hotspot is a feature of iOS that lets iPhones running iOS 4.3 and higher share a cellular data connection with other nearby devices through Wi-Fi, Bluetooth, or USB. This feature is known as tethering.
When you use Personal Hotspot, your iPhone acts like a wireless router for the other devices, transmitting and receiving data for these devices. If you have the available data on your cellular plan, it’s an excellent alternative to using public Wi-Fi hotspots.
