When does the bank card change the mobile phone number prompted by SMS to take effect?

After the bank card changes the mobile phone number prompted by SMS, it basically takes effect immediately. After it takes effect, the system will send a short message to the new mobile phone number. If the SMS is received, the modification is successful. If it is not received, there may be a problem in the intermediate link and it needs to be revised.

SMS reminder, you need to bring your valid ID card and bank card to the bank counter to modify your mobile phone number.
