Set Network Mode Options
In order to roam internationally on different types of network technology (CDMA/LTE and GSM/UMTS), you may need to set your phone’s network mode to allow use of a specific technology. Once set, your phone is designed to enter global roaming mode automatically when you activate your Sprint Worldwide service, meaning that it should automatically connect to an appropriate CDMA/LTE or GSM/UMTS network when you travel.
To set your network mode options manually:
1. From a Home screen, tap Apps > Settings > Mobile networks
2. Tap Network mode to configure options:
l To allow connections to CDMA or LTE networks only, tap CDMA or LTE/CDMA.
l To allow connections to GSM or UMTS networks only, tap GSM/UMTS.
l To allow connections to available CDMA/LTE or GSM/UMTS networks, tap Automatic. This is the recommended setting for international use.
Make and Receive Worldwide Calls
When travelling on international networks, you can place and answer calls as you would on the Sprint network (see Place and Answer Calls), although some additional instructions may be required to place a call. Some features and services are not available in all countries. For more information on services that are available while roaming, visit sprint.com/sww.
