It looks like there is NO ATTACHMENTS with the bundle - it works for text only. I've tested it, and other people have also confirmed the same. So don't get carried away thinking you're downloading pics and videos as part of the bundle, you aren't! They will eat your regular data or airtime. They give absolutely no warning in their ad, so warn your people!
UPDATE: it looks like attachments ARE actually working now, must have been some initial theething issues.
