  • Check for typos, extra spaces, or incorrect encoding in the system_id field.
  • Confirm that the account associated with the system_id is active and not suspended.
  • Enable debugging logs to inspect the exact values being sent in the PDU.

If the issue persists, contact the SMSC provider to verify the validity of the system_id and resolve authentication issues.
