International Calls
Making International Calls from Your Home Area
For information about making international calls from your home area, including rates
and other charges that may apply, contact your carrier or go to your carrier’s website.
Using iPhone Abroad
You may be able to use iPhone to make calls in other countries around the world,
depending on available networks.
Enable international roaming: Contact your carrier for information about availability
and fees.
Important: Voice and data roaming charges may apply. To avoid data roaming charges,
turn Data Roaming off.
Turn Data Roaming off: In Settings, choose General > Network, then tap to turn Data
Roaming off. Data Roaming is turned off by default.
Turning Data Roaming off helps to avoid data roaming charges when traveling outside
your carrier’s network by disabling data transmission over the cellular network. You
can still access the Internet if you have a Wi-Fi connection. If Wi-Fi network access isn’t
available, however, you cannot:
Make or receive FaceTime video calls Â
Send or receive email Â
Browse the Internet Â
Sync your contacts, calendars, or bookmarks with MobileMe or Exchange Â
Stream YouTube videos Â
Get stock quotes Â
Get map locations Â
Get weather reports Â
Purchase music or apps Â
Other third-party apps that use data roaming may also be disabled.
If Data Roaming is turned off, you can still make and receive phone calls, and send and
receive text messages. Voice roaming charges may apply. Visual voicemail is delivered
if there’s no charge; if your carrier charges for delivery of visual voicemail when
roaming, turning Data Roaming off prevents the delivery of visual voicemail.
Important: If Data Roaming is turned on, you may incur charges when roaming
outside your carrier’s network for the use of any of the features listed above, as well
as for delivery of visual voicemail. Check with your carrier for information about
roaming charges.
