GSM protocol

GSM (Global System for Mobile Communications) is a standard used for mobile phone networks that enables voice calls, text messaging, and data services. It works by connecting your phone to cell towers through radio signals, which then route your communication through a network infrastructure to reach other phones or internet services. GSM manages signaling, authentication, and encryption to ensure secure and reliable communication. It is widely adopted globally, providing seamless connectivity and allowing users to make calls and send messages across different countries that support GSM technology.
