What Is A Global System for Mobile Communication (GSMC)?
The Global System for Mobile Communication (GSM) is a European standard for telecommunications used for 2G digital cellular networks. It sets the protocols for mobile phones and devices. In the 2010s, it became a global standard for cellular communication until 2G networks were replaced by 3G. It is no longer in service, but the acronym GSM continues to be used to refer to G mobile phone technologies.
