World phones have the capability of roaming from country to country and region to region, ideally without the loss of any capabilities. While there may now, on the surface, appear to be a great market for this type of phone, in 2000 the United States had 28,065,000 travelers leave the country to visit locations with GSM service. This report forecasts the world phone market through 2005, as well as quantifying the handset and roaming fee revenues.
