Raymond, Sorry for the late reply. GSM frequencies are 900MHz and 1800MHz (DCS) worldwide, except the US, where GSM uses the same PCS 1900 frequencies as TDMA and CDMA. The US 800MHz cellular frequencies also have TDMA and CDMA systems operating. For an overseas GSM user to roam into the US, he would need a handset that uses the US 1900MHz frequencies. So a tri-mode GSM phone is required solely for the US. In Asia and CALA, govts have allocated 800, 900, 1800 and 1900 frequencies, so GSM, DCS, TDMA and CDMA systems are in use. 3G presented a chance to harmonize frequencies worldwide. Most of the world have fallen in line with ITU recommendations except the US. The FCC has now released the 700MHz band, and these will most likely be used for 3G technology, possibly CDMA2000. Since the 700MHz band may take up to 6 years to clear (of the TV broadcasts), it is quite possible that 3G WCMDA will be widely used worldwide on the ITU band, while the US is limited to the 800 and 1900 bands. The story for 3G may be a repeat of the 2G story.
