No kidding, I was checking out Siri on my new iPad with iOS 6 beta installed, suddenly this text message from my carrier just pop up from nowhere. I assume it's an SMS because they send these data reminder messages to phones and 3g dongle users all the time, but I was never able to read them on my iPad since it doesn't support SMS without a jailbreak. Now it does, weird. BTW the pop up looks like an old iOS notification, and when I clicked OK it's completely gone, not in notification center, nothing in the Messages app. Has anyone experienced the same thing? Or it's me having delusions. THX.
