Chapter 3 Phone 45

International Roaming

You can use iPhone to make calls in many countries around the world. You must first
enable your carrier’s service plan for international roaming.
So that you can still make calls by tapping entries in contacts or favorites, you can set
iPhone to add your country prefix automatically to phone numbers when you’re calling
from another country.
When you’re traveling outside your carrier’s network, you may be able to choose
among different carriers in the area where you’re traveling.
Note: Roaming charges may apply. To avoid roaming charges, make sure Data Roaming
is turned off.
For information about making international calls, including rates and other charges
that may apply, contact your carrier or go to your carrier’s website.
