How do I view a detailed SMS report?

I just did my first SMS campaign. I can see the number sent, successful, opted out, and bounced. But I cannot click into the list and view the contacts like I can with an email campaign. How do I see these details? I imported an old list where I had previous consent, but it appears that some of those numbers are invalid. I'd like to flag them for follow-up. The export of the specific list I sent to does not seem to show these details either. Thanks in advance!
