I'm creating an automation to import people from a CSV list into a MobileConnect Contact List. I've created the Import Definition. After i dragged "Import Mobile Contacts" to "Step 1", i got empty SMS folder. I don't understand. Does this mean the import definition is not under SMS folder? Or raw files are not on sftp?
If you want to import data from a CSV via an automation. You need to create an import activity inside Contact Builder. Then you decide to push the data SMS all contact or a specific list.
In Automation Studio, you should have access to this import via Import Activity or via Import Mobile Contacts.
