GSM

GSM, or Global System for Mobile communications, is a standard technology used for mobile phone networks worldwide. It enables your phone to connect wirelessly to nearby cell towers, allowing voice calls, text messages, and data transfer. GSM works by dividing the coverage area into small zones, which helps optimize communication and protect your privacy. It also uses digital signals, improving sound quality and security compared to older analog systems. Essentially, GSM is the foundation that allows your mobile device to communicate seamlessly over cellular networks around the globe.
