Why is there no SMS prompt for opening online banking?

If only online banking is enabled and there is no SMS reminder, SMS reminder needs to be enabled. For example, the SMS reminder service of Agricultural Bank of China is called mobile messenger. The following channels can be used to open ABC mobile messenger:

1, you can sign a mobile messenger through the counter of the business outlet;

2. You can call 95599 telephone banking to sign the mobile messenger contract manually;

3. Bank managers can be authorized to register the mobile messenger service through batch registration;

Charge 2 yuan/month, 24 yuan for one year.

You can cancel the cost of SMS, and you can use mobile banking normally after canceling SMS. These are two different functions that do not affect each other.
