How to Solve It?

Check the SMSC logs for more details on why the broadcast request failed.
Verify if broadcast messaging is supported by the SMSC and that your account has the necessary permissions.
Ensure that all parameters in the broadcast_sm request are correctly formatted and valid.
Retry the request after confirming the issue is resolved with the SMSC.

To resolve this issue, identify the root cause by analyzing the response from the SMSC and correct any configuration or request issues.
