What is the short message number of UNIAUC?

If this English is included in the SMS bill you receive, it generally represents the charge of a certain video platform. Please see if there is a charge. If it is not the case of fee deduction, then there is no corresponding API interface for sending SMS. When you check the bill information, it doesn't show the number. You may not see the message content when querying the bill. UNIAUC is code, which means that SMS has no corresponding API interface.
