European union mandated GSM use.In North America CDMA has wider coverage than GSM.For People going international roaming it advisable to go for GSM technology.
In CDMA technology both voice and data are separated from signals using codes and then transmitted using a wide frequency range.So there is more space left for data transfer.
CDMA has a faster data transfer rate than GSM ,it has a maximum download speed up to 2 mbps.For GSM maximum download speed is up to 384 kbps.For browsing web CDMA is better than GSM.
GSM technology requires a card known as SIM (Subscriber Identity Module) in which contact info is stored.With CDMA your account information is stored into your mobile phone.If you change phone your info must be transfered to new phone.
