The last page of your weekly or monthly (or custom) reports has a section called "SMS Replies"
Very simply, this represents people who voluntarily replied with "OK" and received their trade appraisal on their cellphones.

Our SMS system doesn't link to your staff or your business in any other way.
This helps you to avoid issues such as text spam law problems etc.

This is strictly to let you know how many replied - a gauge of accuracy of the cell phone number.

Thanks to Willy Sullivan of American Eagle Harley-Davidson for his question.
