Why Can an SMS Sending Request to an Incorrect Recipient Number Be Successful?

The Message & SMS platform does not validate recipient numbers. The successful request of calling an SMS sending API does not indicate that the SMS message is sent successfully.

The Message & SMS platform checks whether SMS messages with the same content are sent to the same recipient number. If so, the platform sends only one SMS message to the recipient number and returns the status code E200041 for other SMS messages.

After the request is successfully sent, the Message & SMS platform returns a status report within 72 hours. If the platform fails to send an SMS message to the recipient number, a status code that indicates the error cause is returned. For details, see SMS Status Error Codes.
