I concerned that I will be separated with my family as I will move to Europe, presently I stay in U.S.A. so I am planning to buy a prepaid international cell phone so that I do not have much burden on my pocket when I am in international roaming. But I don’t have much idea about the pre paid international cell phones, such as what are the call charges and how much rental I have to pay for it. if any one of you have such experience that shear your experience that in which way it will going to help me when I move out of country?
