Reliable SIM data management throughout the entire SIM lifecycle


SIM card data management has always been an important activity for MNOs. Over-the-air (OTA) is a cost effective way to manage SIM data such as SMSC GTs, network brand name, preferred roaming networks, dual SIM numbers, etc. Silent SIM updates and changes (requiring no subscriber intervention) has been further simplified and automated by Opencode.

Opencode SIM OTA Center provides secure multi-vendor card management throughout the entire SIM lifecycle. Based on Opencode’s years of world-class core messaging and signalling experience, the solution offers a full range of support and management tools for maximum performance.


Flexible acquisition, deployment and over-the-air transport options

The platform, delivered either on CAPEX or OPEX model, can be hosted locally or as a service in the cloud. The solution can be deployed with the MNO’s existing SMSC or more efficiently with a built-in SIM OTA SMSC. Other over-the-air transport options could be USSD and IP.

Example of integration:
