Using Your Device While Traveling
Your device is designed to enter global roaming mode
automatically when you enable your Sprint Worldwide
service, meaning that it should automatically connect
to an appropriate CDMA, GSM, or UMTS network when
you travel. Upon arriving in a country with CDMA voice
and GSM voice and data coverage, you must change
the device to
GSM only mode to be able to access data
services. You will need to change your device back to
Global mode when returning home or to a CDMA
destination.

1. Press > Settings > Personal > Phone.
