Why didn't I send a short message to the bound mobile phone when I withdrew money from the bank card in China?

After opening the bank card, there is no information reminder on the mobile phone after consumption because the user has not opened the SMS reminder, and there will be a reminder of consumption information after opening it.

SMS reminder service opening mode:

1. After online banking, click Bank Account-Account Service, select the account to open, and click Next.

2. At this time, I will be prompted to sign the agreement, and I (Party A) will check that I have carefully read and understood the above agreement, fully agree and accept all the terms and contents of the agreement, and be willing to perform and undertake the agreements and obligations in the agreement.

3. Select the service type to be opened, enter the mobile phone number to receive the information service and verify it. Enter and click Add.

4. After successful addition, under the list of new services: click Next.

5. Enter the mobile phone transaction code and dynamic password, and click OK. The bank will deduct two dollars and it will take effect.
