Postal savings short message service prompt urgent.

I wonder which communication company your mobile phone card belongs to. Banks and communication companies are cooperative. When your account changes within the scope of your SMS business, the bank will immediately send data to the communication company and request the communication company to send the information to your mobile phone. In all banks, the system is relatively stable, and the probability of error is very small. Many times, the communication company's system is slow or wrong, and it doesn't need the accuracy of the bank. Causes you to delay sending information or send an error message, or even not send you a message. In addition, some mobile phone numbers can not accept information, or intermittent failure. The reason is that these numbers have been used by some leaders before, or blacklisted, and communication companies have restricted the acceptance of short messages. I suggest you call the customer service of the communication company with your mobile phone number and ask her to solve this problem.
