What is a SIM Gateway Device and How Does It Work? - dinstar - 03-04-2025
A SIM Gateway Device is a telecommunications hardware that allows multiple SIM cards to be used for voice calls, SMS, and data routing over GSM, 3G, or 4G networks. It connects to VoIP systems, enabling businesses to manage mobile communication efficiently. These devices help reduce call costs, support bulk messaging, and ensure seamless connectivity by automatically switching between SIMs. They are widely used in call centers, enterprises, and telecom industries for optimizing communication and reducing operational expenses.
