SIM-box (also called SIM-bank or SIM card reader) – is one of hardware modules of ANTRAX Solution for GSM termination.

SIM-box enables GSM gateway functioning without inserting SIM cards and this feature allows to store a bundle of SIM cards separately from VoIP/GSM gateway in order to minimize expenses on their maintenance.

Key benefits:

SIM box allows you to install and manage from 20 to 300 SIM cards of different mobile operators that enables work of several GSM gateways placed in different locations.

You can keep your SIM cards away from the GSM gateway. It allows you to attach a separate SIM card for GSM/VoIP gateway module, enabling the same card to call from different points thereby reducing the risk of blocking.

Main Features

SIM box (or sim bank) includes the following elements:
- Sub-rack with fifteen universal slots which provides power and cool the system
- SIM-board that comprises 20 SIM cards

Each client has opportunity to choose individual structure of SIM box and use from 300 SIM cards during GSM termination. It is possible to combine GSM and SIM boards in one rack, so it is gsm sim box.

Module-based structure of the hardware of this product 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 when you have several GSM gateways located in different countries or in different regions of the same country and all sim cards involved in termination, may be located in one or more SIM boxes placed in the same spot), etc.

SIM cards rotation. One of the optimization algorithms of the system is the so-called Antrax "SIM-rotation". SIM cards within each SIM box can be divided into groups, each of these groups can be assigned 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 to make calls from every gateway by turn, creating an illusion of subscriber movement, thus helping to protect your cards from blocking by the mobile operator.
