Symptom

When sending SMS to the US or Canada, you receive Rejection Code 10 or Error Code 15.

Applies To

  • Outbound SMS
  • US
  • Canada
  • Illegal Sender

Resolution

For messages to the US or Canada, the Sender ID should be a US or Canadian long virtual number.

Cause

For each API, there is a different error code that indicates that the Sender ID is illegal or invalid for this message:

  • SMPP API: Rejection Code 10 - Source Address - Submission Control Failure

If a different Sender ID is submitted, the message will be rejected with the one of these errors, depending which API is being used.
