How to Set Up and Use Personal Hotspot on iPhone
Ever been stuck in a situation where you need to get a computer or tablet online with no Wi-Fi nearby? If you’ve got an iPhone with a 3G or 4G data connection, that problem can be easily solved thanks to Personal Hotspot.
Personal Hotspot Explained
Personal Hotspot is a feature of iOS that lets iPhones running iOS 4.3 and higher share their cellular data connection with other nearby devices via Wi-Fi, Bluetooth, or USB. This feature is generically known as tethering. When using Personal Hotspot, your iPhone acts like a wireless router for the other devices, transmitting and receiving data for them. If you have the available data on your cellular plan, it’s an excellent alternative to using public WiFi hotspots.
