Unfortunately the GSM chipset of the Neo1973 SHOULD support 850, 900,
1800 and 1900 MHz, but some user reports say that 850 is not working
with the currently delivered version. I have not read any statement
from an official side if this is true and if it is due to software
(firmware) or hardware problems.
There is of course not such a thing as "analog" connectivity with a GSM
chipset. GSM by definition is digital.
