Why is there no information reminder on the bank card?

1. SMS reminder service is not enabled on the bank card, or the mobile phone number is reserved incorrectly.

2. The change amount did not reach the SMS reminder amount.

3. The mobile phone or operator blocked the short message number of the bank. Settings can be changed for mobile phone problems, and customer service can be consulted for operator problems.

4. Problems in the banking system cause delay, or poor signal also causes information delay or non-transmission.

5. SMS fee deduction is unsuccessful for two consecutive months, and the status is arrears, and SMS reminder will not be sent.
