Well I am flying on a big trip on tuesday night. I will be going alone, and need a way to get in contact with everybody. My at&t go phone account expired, and now I am cell-less. I have a nice phone and just use an att sim card. They said I needed to buy a new sim card, and set up a whole new account. I don't want to do this. What is the best prepaid plan available? I hear boost is good, but the way I understand it, you have to buy one of their phones. I already have a nice unlocked phone. Please help!! We dint have a Virgin Mobile store here, and I don't have time to have a sim card delivered
