China Construction Bank 95533 sent a message saying that I signed a short message bank. What happened?

There should be no charge. You can ask if you want to open it.

The so-called SMS banking is actually a reminder service.

Notice of change of personal account balance, including:

1. Incoming account information notification

2. Notification of transaction information

Personal deposit maturity notice

Personal loan collection notice

Bank card information notification

Risk early warning notice

Personal account information inquiry

Notice and inquiry of financial investment information

Repayment information

There are also some short messages to promote banking business. After opening this service, if there is any change in your bank card, we will inform you by SMS again. (I think it's really useless)
