1、Overview
VoIP GSM gateway (GoIP gateway) is a device that can reduce the cost of calling mobile networks from fixed telephone lines. It can route directly between IP, digital, analog, and mobile networks. GoIP gateways are increasingly being used by telephone operators to connect IP calls to mobile networks. In areas where fixed line services are unavailable or much more expensive than mobile costs, GoIP gateways are an irreplaceable alternative.

The following figure shows a basic topology of GP Gateway usage.

This linked product with eSIM，eSIM (embedded SIM) is a tiny digital chip built into devices (like phones, tablets, or gateways). By applying to the operator for eSIM data to be written into the device's blank card chip, all functions of the physical SIM card are achieved;  that replaces physical SIM cards.
