The GSMA requires you to have Near Real Time Roaming Data Exchange (NRTRDE) fully implemented and running by 1st October 2008.
MACH can help you to be at the forefront and can now already begin to detect possible fraudsters on your network. To test where you are on the path to becoming fully compliant with NRTRDE please click here.
