工商和招商两个 visa 卡都提示这个： We're unable to complete your sign up. Common sign up errors are due to: (a) Using prepaid cards. Oracle only accepts credit card and debit cards (b) Intentionally or unintentionally masking one's location or identity (c) Entering incomplete or inaccurate account details. Please try again if this applies to you. Otherwise, contact Oracle Customer Service . 大家有遇到类似问题，后来又成功了的经验吗？
