What is a GSM Gateway and how does it benefit businesses in communication?

[ruhiparveen]

A GSM Gateway is a device that connects a business's communication system to the GSM mobile network, allowing voice and SMS communication through mobile networks. It acts as a bridge between landlines, VoIP systems, and mobile phones, enabling businesses to make calls and send messages via SIM cards instead of traditional phone lines. This reduces communication costs, especially for international calls, and enhances flexibility by supporting multiple networks. It also provides better scalability, as businesses can easily add or remove SIM cards based on their needs, improving efficiency and reducing overhead costs.
