In the settings application on the iOS device, go to the cellular screen. There are a number of different toggle switches in this screen, including the speed of the over-the-air network you can use. When turning the iPhone into a hot spot, the device should also be set to access LTE networks whenever available if that is an option.
At the bottom of the settings cellular screen is a toggle switch for activating the personal hot spot. Touch this button, so that the toggle switch turns green. This means that the hot spot is active.
When the personal hot spot switch is toggled on, connect to a WiFi network being broadcast by the iPhone. Some carriers do not offer this function at all, and if it isn't working you may not have permission to use the feature.
