Verification conundrum

I want to start doing some FBML stuff on my website, which requires making my site a FB app. Fine, but that requires verification. Fine, I do have a cell phone. But I live in Japan, where the text messaging system is different - anyone can send email to any cell phone using the mobile email address, but only cell phones in the same mobile network can send short messages via just the phone number. Since Facebook’s server is not a cell phone in the same network as mine (in fact, not a cell phone at all), that verification method doesn’t work. Anyone know if there is another way? (No, I am not affiliated with a university, and I don’t want to give out my credit card number if I can avoid it.)
