I am trying to send an SMS from Journey Builder using contact data for mobile number as opposed to an entry source attribute. The SMS does send but only to contacts who are already in the MobileConnect list. These contacts entered the list in a previous journey where I used entry source data and subscribed them to a key word.
The settings for my new journey are:
- Entry source is a data extension
- Subscribe Contacts to a key word
- Use mobile number attribute from Contacts
The entry source DE for this journey does not have a mobile number but I have linked an attribute set which includes this in data designer. The number includes international code and there is a locale field.
Are there any suggestions on how I can send SMS using contact data to contacts who are not already in the mobile connect list?
