How to Use iPhone As a Modem

If you need access to the Internet from your computer when traveling, and can't find a Wi-Fi hotspot, use your iPhone. Your iPhone can provide your computer and other devices access to the Internet using a feature known as Personal Hotspot. This feature makes it easy to use USB, Bluetooth or Wi-Fi to share your iPhone Internet connection. Keep in mind that your cellular plan must allow this feature, so check with your provider before heading out on a trip.
