Apparatus for identification of locations within a cellular network subject to loss of roaming users, comprises a monitoring unit for monitoring International controlling signaling of the cellular network, a register for registering cancel signals associated with roaming cellular telephones leaving the cellular network, and a query unit, for responding to the cancel signals by issuing a query to identify a current cell location of the cellular telephone. The cell locations indicated can then be aggregated to show where there are problems with leakage of roaming users.
