I have a cingular Treo 650 UNLOCKED. I rented a sim card from Cell Hire for my two week stay in France. The card does NOT include a data package. It is ONLY voice. I am getting MUCH better rates than if I just used Cingular's international roaming etc. I was planning on swapping sim's when I want to use the data service. Can anyone advise on a company that has either pre-paid or rental sims that have data services in France? Orange?
