A GSM Gateway, also known as a GSM VoIP Gateway or SIM Box, is a device that connects a GSM network to other networks, such as VoIP or traditional landlines, enabling voice calls and SMS messages to be routed between them. It is often used to reduce communication costs by bypassing standard mobile network charges, allowing calls to be made via the internet or alternative networks. GSM Gateways are commonly used in businesses for applications like call centers and unified communications systems.
