Mark's son is about to be stationed in Japan and wants to know if he can bring his phone along. Leo says that he can, but he'll need to get the phone unlocked so he can use a local carrier. There may be issues with radio frequencies, though. He should check out the website prepaidwithdata.wikia.com to learn about what carriers and phones are best. He should also ask his US carrier if he can suspend his account while he's overseas so he won't have to pay for two services while overseas. The chatroom says that Verizon has a military plan and that may be a good option.
