GSM
Mobile network protocol
GSM stands for Global System for Mobile Communications, the digital cellular network standard that became dominant worldwide in the 1990s and 2000s.
A GSM phone uses a SIM card, allowing users to swap devices while keeping their number.
The term persists even as networks have evolved: My old GSM phone won't work on the new network.
In textiles, GSM means grams per square meter, measuring fabric weight: This cotton is 180 GSM.
