Why didn't China Bank Card inform you of three yuan this year?

Probably because my mobile phone is in arrears, I can't receive the SMS notification.

The reasons for this may be as follows: First, the fund balance of the bank card account has not changed. Second, the change amount of bank card fund balance is lower than the set notice amount. Third, the sent SMS notification was intercepted by the mobile phone as unsafe information. Fourth, the text messages sent are automatically attributed to spam messages by mobile phones. Fifth, there are too many short messages on mobile phones, and the space is not enough to accept. Six SMS notification functions failed to deduct money, and the SMS notification function was frozen. Seventh, your mobile phone number was cloned and the text message was sent to someone else's mobile phone. Eighth, support short messages. The short messages sent to you inform you that you can't receive them. Nine is the bank's operational error, not sending it in time or not completing the setting. Ten is that the mobile phone is in arrears and can't receive the SMS notification.
