check out their coverage map & other features

yes you can. But a prepaid international call placed on a cell phone will be billed at a higher rate and shorten your actual calling card time than if you use a land phone Use the prepaid card on your cellphone when you have free mins(say if you have unlimited weekends or weeknights) otherwise, cingular will only deduct your whenever mins from your plan.
