GSM is the common mobile communication standard that currently has the greatest coverage. If your device supports this connection, you can send messages, make calls, and even access the Internet. Upon closer examination, one can conclude that the GSM standard refers to the second generation of mobile Internet, put – 2G.
El alcance de la red no supera los 120 kilómetros, pero dada la ubicación actual de las torres de telefonía, esta distancia es suficiente. El principal inconveniente, por el que los fabricantes empezaron a instalar módulos 3G y 4G en sus smartphones, es la baja velocidad de procesamiento de la información en las redes GSM. Es decir, la velocidad de transferencia de datos no superará el umbral de 474,6 kbps.
However, despite the significant disadvantage, the GSM communication standard is characterized by low battery consumption. If you want the phone to work only with GSM networks, then follow this path: “Settings” → “SIM cards and mobile networks” → “SIM card settings” → “Preferred network type” → “2G”.
