Frequency Band
GSM operates in a number of different frequency bands, where available. 900 and 1800 MHz are
used in Europe, Asia, Australasia and Africa, whilst the 1900 MHz band is used in North and South
America. By default your GC79 operates in 'tri-band' mode and automatically finds available networks
in any of these frequency bands. It is not recommended to change this setting. See GSM Performance
and technical characteristics on page 68 for a list of GSM frequency ranges.

voicemail service. However you can make and answer fax and data calls, providing you have
appropriate software on your PC to handle them.
