A SIM Bank, also known as a SIM Box, is a device used in telecommunications that houses a large number of SIM cards. These SIM cards are used to connect to cellular networks and are mainly employed in applications such as bulk SMS sending, call termination, and mobile marketing campaigns.
There are two main components to a SIM Bank system:
- SIM Bank Server: This is the hardware that contains slots for inserting SIM cards. Depending on the model, a SIM Bank can house anywhere from tens to hundreds of SIM cards. This server is responsible for managing the SIM cards, including their operation, storage, and maintenance. It also monitors the real-time operation status and controls each independent SIM card.
- SIM Bank Control Software: This software is responsible for managing and setting up the routing for the SIM cards. It works in conjunction with the server to allocate and manage resources. The software often includes features like SIM rotation, operation scheduling, and safety settings to prevent SIM blocking by network providers.
In the context of a GSM gateway, a SIM Bank can help manage a large number of SIM cards, and distribute calls to different SIMs to avoid the suspicion of network providers and reduce the chance of SIM blocking.
While SIM Banks are beneficial for managing bulk telecommunications operations, it’s important to note that their usage should comply with local laws and regulations, as misuse can result in legal penalties.
