Turn international data on or off
1. From the Data usage screen, select International Data Roaming. 
2. Select the International Data Roaming circle.
Note: Data roaming is off by default. Enabling Data roaming will allow the device to attach to foreign wireless network signals when available. International roaming charges will apply.
