Adding the new iPad data plan to my existing at&t account

It doesn't work the way you envision. At the moment, you can only pay in advance by credit card. Here's AT&T's Data Fact Sheet.

You'll need to call AT&T or visit an AT&T store and ask if they can do that. My understanding is that the data plan for the iPad is a completely separate plan, but perhaps there's a way they can bill you for both accounts on a single bill. Only AT&T can answer that for you.

Regards.

It is highly unlikely. At&T has set this up as a rolling 30 calendar day system that is paid in advance by Credit Card, and can be turned on and off, or changed, at will. It is also a program that is 100% automated, and requires much less customer service support and interaction. If you set it up on your credit card, and do not wish to change it, the billing setup is perpetual, and should require nothing on your part.

About that, I'm going to have to slog over to my AT&T store because they're saving money by automating all of this. I can't sign up for the iPad 3G plan because my billing address on all my credit cards is a PO Box. The signup procedure won't accept this. My credit card companies don't have a problem with it, but AT&T does. Yeah, I'd bail on AT&T in a heartbeat if another cellular company supported the iPhone in the U.S. without having to use a jailbreak.

Is that true? No PO Boxes? That's going to be a problem. Are there gift cards or something?

When I tried to sign up for the unlimited data plan directly on the iPad 3G, I got an error saying that PO Boxes are not acceptable billing addresses and that I should use a credit card having a street address. For security purposes, my wife and I have ALL our billing addresses set to a PO Box. This is RIDICULOUS. If the credit card company doesn't mind, why should AT&T?

I had this issue once before. I'm pretty sure I can modify my credit card billing address on-line, make the purchase, and then change it back right after the purchase is accepted.

That should work here for me...give it a shot.

Thanks, but I tried that. Apparently, their automated system is checking the validity of billing addresses. When I used my street address, I got an error saying that the billing address was incorrect. I'm stuck here. Thinking about returning the iPad.

Oh, wait, you mean WITH the credit card company! Great idea! I'll give that a try. Thanks VERY MUCH!

That did it. Thanks again!

Great! Now I know it will work for me!

I've got the same problem. I changed my billing address to my physical address and it still won't activate. The credit card company says the authorization requests are coming in and being approved. Still no data plan. AT&T *****.

It makes no sense that your credit card company would only allow you to make purchases when using your PO box. Your PO box is just your billing address and many companies won't deliver or use a PO Box except for billing only. However, they usually insist on your physical address for sending out packages etc. My credit card company allows me to make purchases using either my PO Box or my Physical Address, yours should too, unless YOU have it restricted. You can call them and usually they can go right into the system and add your physical address so you can make the purchase.

My card company (Disc) said it would not show up until after midnite.
