Two configuration sof sim box are available, one for 60 sims and another one is for 120 sims. One system can include as many simboxes as you wish, which gives you ability to use any amount of sims in your termination system.

Module-based structure of the product hardware opens up a wide range of possibilities to its users, such as:

  • SIM cards could be placed separately from GSM modules (this option will require high-quality Internet connection between GSM-gateway and SIM box);
  • SIM cards which take part in termination of voice traffic and sms termination to different destinations/countries could be placed in the same spot, making it easy to control their activity. It is important to have several GSM gateways located in different countries or in different regions of the same country. All sim cards which are involved in termination may be located in one or more SIM boxes placed in the same spot;

SIM cards rotation. One of the optimization algorithms of the system is so-called Antrax “SIM-rotation”. SIM cards within each SIM box can be divided into groups, each of these groups can be attached to a separate GSM-module of VoIP-gateway. Over time, the system is able to make changes within each group, changing SIM card which is responsible for making voice calls from one to another.

This not only allows you to optimize resource consumption of every single “Sim”, but also gives a possibility to reduce their workload and, consequently, the suspicion of the mobile operators.

SIM cards migration. Antrax system is capable of registering the SIM cards on different GSM-modules with a specified frequency. If you have several GSM gateways located in different parts of the city, system will make SIM card conduct calls from every gateway in turn, creating an illusion of subscriber’s movement. This will help you to protect your cards from being blocked by the mobile operator.
