Purchase data package payment failed

[ff18]

我刚装了 10 磅，我想买一个 10 磅的数据包，但是当系统说需要额外的付款人身份验证才能完成付款时，这意味着什么？如何操作？

I just loaded up 10 pounds, I want to buy a 10 pound data package, but what does the system mean when it says that additional payer authentication is required to complete the payment? How do I operate?Purchase data package payment failed
