WORLD WING
WORLD WING is the DoCoMo's FOMA international roaming service that enables you to place
or receive a call using the same mobile phone number even if you are overseas, just by using
the UIM (green/white) and a WORLD WING service-compatible FOMA terminal.
※ If you subscribed to the FOMA services after September 1, 2005, you already have WORLD
WING and no application is required. If you declined to use WORLD WING when you
subscribed to the FOMA services or cancel the WORLD WING service halfway, you need to
make an application again to use WORLD WING.
※ If you subscribed to the FOMA services before August 31, 2005 and did not make an
application to "WORLD WING", you need to make a separate application.
 This service is not available in some service charge plans.
 If you should lose your UIM (green/white) or have it stolen abroad, please report it to
DoCoMo and take steps to cancel the use of the UIM as soon as possible. For information
on where to call, see "General Contact" on the backcover of this manual. Note that you are
still liable for the call and communication charge incurred after the loss or theft occurred.
