C.4 Changing the operating frequency between
EU/Rest of world and US wavebands
In Europe and much of the rest of the world GSM communications happens either
in the 900 or 1800 MHz band (check with your local service provider). In the US
and some other countries the 850/1900 MHz bands are used. To switch to
alternative bands the modem must be connected to a PC and a command issued to
change the setup.
