We have configured the SMS vendor in ACS instance under external account. And adobe team confirmed that the configuration is correct. And then I have tested the SMS configuration by triggering test SMS to few customers(Mobile numbers are valid and not in DND list). But the status of SMS delivery is in "pending status". Could you please help me ,to find the issue/fix the issue.
And Could you please let me know that from where can i get the MTA log file?
