- At a minimum, they must support the following frequencies of GSM:
North America: 850 MHz GSM/GPRS networks
North America: 1900MHz GSM/GPRS networks
Europe/Asia Pacific: 1800MHz GSM/GPRS networks
Europe/Asia Pacific: 900MHz GSM/GPRS networks
So a run of the mill North American GSM phone that is not a world phone would only support 850/1900MHZ. The Vzw world phones add cdma frequency support in addition to the 4 GSM bands.03-21-09 06:08 PM
- Pete6Retired ModeratorMost countries use the GSM (Global System for Mobilse) standard for their cell or mobile phones.
The US was slow to adopt a common standard and until a few years ago there were divers systems across US geographies and carriers. So a phone bought in one city often would not work in another. It was a mess. The US did not want to be a late adopter of GSM which was now seen as being a bit out of date.
Slowly the market forced standards and GSM spread across the States but by now, CDMA (Code Division Multiple Access) had appeared and many think that it is a superior system. Certainly it is newer.
Several carrier adopted CDMA and thus users having such phones could not use them outside the US coveage area.
RIM made a special phone model that would support both CDMA and GSM. They called it the World Edition or WE and it allowed users to run with CDMA in the US on their home carier and when they went globe trotting, they could use GSM.

- If you can wait till the 9630 comes out on Verizon, I predict a lot of Storm owners will be selling their Storms to recoup some of the money they had to pay buying the 9630 at full retail price. The price on unlocked Storms should also come down after the release of the 9630.03-21-09 06:30 PM
