How to check for status on my International Day Pass order?

Also according to AT&T once they detect your phone is roaming they would send you a text message if International day pass had not been added to any particular line. Responding yes to the text message add international day pass.

I would not wait for this to happen, I would log into my account and add it before you go.

You can just log in to verify it's on your line. You can add it if it's not. 

(I'm not sure how you "ordered" it).

Last week I realized it wasn't on all my lines, so I added it on the website, and they also sent me a confirmation email.

prepaid or postpaid and where are you traveling too?

I did it all while logged into my online account.  I want my line along with a 2nd line to have the ability to use data while in Europe.  This is for postpaid lines.  The countries we're visiting are on the list.

Then to check, log back in. Go to where you'd add it and see if it's still enabled...

To add day pass to the second line, you need to select that line and go to the international options section.
