Note: This feature was removed in DME 4.1 SP1.
Statistics in the form of voice/data traffic and consumption are transferred to the server at every synchronization. These statistics can be used in combination with the Analyzer tool in any number of ways - you can for instance monitor for extraordinary usage patterns, use the data as input to budgets, or use the data when negotiating contracts with mobile operators. See Appendix D: Traffic logging for more information.
Furthermore, you can specify various cost-reducing parameters to the use of the device when a user is roaming. See the Roaming section in the user guide for any DME 3.0 client (except iPhone).
