SIM Resource Management Made Easy

For mobile network operators, effectively managing the lifecycle of telephone numbers and associated SIM resources is a fundamental requirement. From both a competitive and regulatory perspective, a high degree of competence in this area is a vital ingredient for a successful operation.

Yet number management isn’t straightforward. Planning is required for number utilization to ensure the MNO doesn’t run out of numbers that can be assigned to new customers. Utilization targets must be met in order to receive additional numbers. Contaminated or ported out numbers must be ring-fenced.

Evolving Systems has developed the best-in-class resource management solution to support mobile network operators adoption of public cloud and web scale architectures. Evolving Systems’ Total Number Management Solution (TNM™) delivers the ability to manage Telephone Number inventory and resources seamlessly and with confidence. This enables MNOs to:

  • Follow regulations with respect to how long a phone number can remain in an ordering, reserved or aging status
  • Return ported-in numbers to the block holder when the service is disconnected
  • Accurately manage IoT/M2M identifiers (EIDs, etc.)
  • Seamlessly automate resource management BSS workflows thanks to TNM’s Standard Resource Inventory Management REST API

  • Deploy and scale resource management rapidly and cost efficiently thanks to TNM's public cloud support
