I'm moving to Japan at the end of this scholastic year to continue my education over there, and since I'll be there for more than 2 years I was going to get a full on post-paid cell phone plan, but after doing some research it seems the legal age to sign up for a contract is 20. I'm only 18 (I will be 19 by the time I get moved) and my parents aren't going to be there to sign the contract as my benefactors. Could they sign up for it online somehow so I don't even have to go in to the store? Would they make an exception since I am the legal age to sign a contract here in the US and I will still effectively be a US citizen while I'm over there? I could get a pre-paid phone to use for a year until I'm 20 but I was planning on jumping off the plane and getting a phone right there in the airport and I'd rather not have to deal with having to get a new number after that. Any other ideas would be greatly appreciated. Thanks.
