AT&T Family Plan Unlimited Upgrade

[Blackbird17k]

So I have the old AT&T family plan unlimited.

I just placed an iphone 5S order for the main line. No problem.

Now when I try to place an order for the secondary link at the apple website, I get an error saying it can't do the eligiblity check. I checked both lines a few days ago, and both were eligible. I log in to my AT&T account, and it says that the main line (which I just ordered a new iphone 5S for) is eligible, but the secondary one isn't.

Any suggestions on what to do so I can upgrade both my lines?

I got in touch with apple. They told me just to order multiple phones based on the "primary" line, and then I'll have to call AT&T to get them activate on the right number. So I did that.
