What is the difference between GSM and GSM 850?
GSM 850 is simply GSM technology operating in the Cellular (850 MHz or "800") frequency band. Both the technology and frequency band have been around for many years, but not until 2002 were they combined. In the U.S. prior to 2002, GSM technology only operated in the PCS (1900 MHz) frequency band.What is GSM-1900 and GSM-850?
GSM-850 and GSM-1900 GSM-1900 and GSM-850 are used in most of North, South and Central America (ITU-Region 2). In North America, GSM operates on the primary mobile communication bands 850 MHz and 1900 MHz.

In 2002, GSM began operating in both the 850 MHz frequency band and the 1900 MHz frequency band, which had been the only band used before GSM 850. Those bands however only work in the US, and therefore unless you have a quad-band phone your phone will not work in Europe and Asia where GSM 900 is used.What is the difference between 800 MHz and 850 MHz?
Before the existence of GSM 850, the Cellular band was commonly referred to as the "800 MHz" band. "850 MHz" implies a different frequency band, but this is not the case. "800 MHz" and "850 MHz" refer to the exact same frequency band.Related Articles
