AT&T email says, "Your Data Plan was cancelled..."

[Dataquest]

I just got an email from AT&T:

Your data plan was cancelled at your request or because it has been inactive for an extended period of time.

If you wish to re-subscribe, please visit Settings on your iPad.

Thank You,

I didn't cancel it and I use it very much every day! It just renewed automatically yesterday. Anyone else get this???

I don't know about your situation but we were testing two iPads with one credit card account. We canceled one of the iPad's services and both got shut down with the same email you describe.

Bug in billing?
