Data roaming sound

This option controls whether the phone should play a sound when opening a data connection on a roaming network. This can help alert the customer to the fact that they are on a roaming network and that therefore their data cost may be higher.

Note that on a smartphone, data connections may be initiated even while the phone is not being used and in sleep mode, and therefore the sound may not be heard before data is used. It should not be thought of as a protection against high data charges associated with roaming.
