Buying train tickets online failed because the card has not signed the SMS service of Agricultural Bank of China. Please sign and try again.

Online train tickets are generally paid by online banking, or bank cards of various banks are used. Generally speaking, online banking payment is more troublesome, and it requires a dynamic password card or online banking shield, so I usually use express payment to buy train tickets.

In fast payment, in order to ensure the safety of your funds, you need to confirm the verification code through your bound mobile phone and open SMS service. Therefore, it is impossible to make online payment with a bank card without SMS service.

You said that the ABC card didn't sign the SMS service, which definitely belongs to this situation. I suggest you take your ID card to the bank to open SMS service. This service is charged and may vary from bank to bank. Generally, it's 2 yuan every month. )
