I just changed my reserved mobile phone number today. Why can't I get the message of SMS notification?

Modifying the mobile phone number reserved in the bank requires on-site verification and verification code; If the changes are verified, there will be no problems in the banking system. There may be four reasons for not receiving SMS: First, the original SMS notification left the old mobile phone number, and then the SMS notification number must be modified again after modifying the reserved mobile phone number; Secondly, SMS notification may not have been opened originally, and there is no link to SMS notification after modifying the reserved mobile phone number; Third, you may not pay attention to the initial amount of notification when you send a text message. If the initial amount is relatively large, you will not receive a small amount of information; The fourth possibility is that the mobile phone security setting or security mode will automatically set the bank prompt number as Do Not Disturb information.
