If ever you find yourself in an area without WiFi, you can establish a network connection using the cellular network of your mobile device by creating what is called a personal hotspot. Once a hotspot is created, you can access the internet by either wirelessly connecting your phone to your computer or tablet or by physically connecting them with a USB cable. This article will teach you how to use your iPhone's personal hotspot as a modem for your other electronic devices.
Before beginning, please note that tethering options are available to iPhones running iOS 4.3 or higher. Make sure that your data plan allows internet sharing. Some mobile operators do not support tethering options, and those who do may charge data tethering as an added "extra" on your monthly data plan.
To create your mobile hotspot, you must also be in an area with good cellular coverage (3G or 4G).

Depending on the model of your iPhone, several sharing options are available to you. Here is a quick rundown:
