GSM stands for Global System for Mobile Communications, which is a standard developed to ensure that mobile networks operate on a unified framework, allowing interoperability between devices and networks worldwide. This standard was initially designed for 2G mobile networks, but it has since evolved to support 3G and 4G technologies. The term emphasizes its global applicability and the fact that it provides the underlying technology for the vast majority of mobile phones and networks globally.

The primary focus of GSM is to define protocols for second-generation (2G) digital cellular networks, enhancing the user experience by allowing features such as SMS, international roaming, and data services. It has become a foundational technology for mobile communications, facilitating not just voice calls but also SMS text messaging, internet data access, and various other services across the globe.

Other options, while they may sound plausible, do not represent the widely recognized standard associated with GSM in telecommunications, as they either misphrase the meaning or refer to non-existent specifications.
