Make sure data services is turned on

Manage Connections icon – Mobile Network Options

Data Services: On

Make sure Network Technology is set to Global or GSM/UMTS

Also try registering your Curve on the mobile network

Options icon – Device – Advanced System Settings – Host Routing Table

Press the Menu key and select Register Now

You will receive a message when the registration is complete
