Windows Mobile, Symbian, and UIQ 3.0 devices are able to collect information about voice usage. When a device user initiates or receives a call, the following information is recorded on the device:
Most network operators provide a roaming service, which allows users to use their phone even if they are not in their home coverage area. When roaming, the user of the phone effectively rents the use of the network of another network operator.
When a user is outside his home coverage area, for instance if a French DME user goes on a trip to Norway, he will not only have to pay a roaming for calls that he makes, but also for calls that he receives.
Mobile country code (MCC) - the country of your location
Mobile network code (MNC). Together with the MCC, the MNC uniquely identifies the mobile phone operator/carrier that handled the call at your end
Name of operator as retrieved from the relay station. Note that since the operator name can be spelled differently depending on which relay station you pick it up from, you may want to edit the name in the database in order to be able to group properly by operator. Contact your DME partner about this.
The phone number dialed or received
The direction of the call - incoming or outgoing
The starting date and time of the call, including time zone information
The duration of the call
This information is used for building the statistics database on the server, if the logging functionality is enabled (see Enabling traffic logging).
