> I wasn't trying to establish that they had stopped, I was pointing out that they adopted it quite some time ago. My apologies, I wrongly assumed we were talking about the current network landscape. You would be correct. > Hasty interpretation of https://en.wikipedia.org/wiki/GSM_frequency_bands https://en.wikipedia.org/wiki/GSM_frequency_bands at least indicates that different frequencies were used in different areas. If memory serves. In the US it was GSM1900 up until the late 90's/early 2000's, AT&T Wireless decommissioned their legacy TDMA network at the time on 850mhz and shifted to using 850mhz for GSM due to better rural signal propagation. Worldwide outside north america's 850/1900, there is 900/1800, and to a much lesser extent maybe 450 for siberia, and in other places likely better served by satellite.
