When my Alipay opens the fast payment (including cartoon) service and binds the China bank card, it reminds you that you have not pre-stored your mobile phone number in the bank.

I also met this situation at the Agricultural Bank of China today. When the bank card was opened, there was a SMS reminder, and the mobile phone number was the same as when Alipay opened the fast payment, but the reminder was that the mobile phone number was not reserved in the bank. I guess mobile phone number reservation and SMS reminder are two concepts. People in the bank only open SMS reminders, and the mobile phone number is not bound to the bank card, so Alipay prompts that the mobile phone number is not reserved. Many bank tellers are not familiar with Alipay's business, so it is better to find a male teller than a female teller, because men know some computer knowledge.
