To disable data when roaming

You can prevent your phone from transmitting data over other carriers’ mobile networks when you leave an area that’s covered by your carrier’s networks. You can still transmit data with a Wi-Fi connection when Global data roaming access is restricted. This is useful for controlling expenses if your cell plan doesn’t include data roaming.

1. From the Home screen, touch and hold the Recent Apps Key (in the Touch Keys bar) > Settings > More... > Mobile networks > Global data roaming access.

2. Tap how you want to restrict global data roaming. Choose from Deny data roaming access, Allow access only for this trip, and Allow access for all trips.
