AT@T data overage after IOS 6 update.

I've not had any problems.

Have you restored your phone as NEW? This has helped some users.

I've noticed the same thing. On the 19th i had 627.7MB and now on the 1st im at 1,843.22, that's also with being on wifi most of the time. I have not been over 50% of my limit in a long time and now I'm close to going over. Hopefully I can make it till the 12th without going over.

I have had this happen to me. Brand new iPhone 5, setup from scratch. I went from 464MB usage to 5GB in one night. At a concert hall. With no service. AT&T supposedly is unable to lift the throttling on my account, as it's "an automated system". I'm stuck with dial-up speeds until the end of the month.

Restore to new doesn't work. 4 gbs since the 25th. Only thing AT&T and apple suggest is turn off cell data when on wifi.

Oh yes ... That's why I bought a smart phone ... To disable the thing and turn it into a regular phone.

Nice that AT&T is crediting the overage charge but seriously- a fix to Verizon but AT&T is just ignored as no problem exists?

Right now - on wifi - in standby- battery has dropped 10% in less than 30 mins and 2 Meg's of cell data. All apps closed and in standby.

Yup. No problem here - works great (sarcasm intended).

I have an iPad2 and an iPhone5 both running iOS6 and using the AT&T network.

My iPhone does not appear to be exhibiting any problems, but my iPad allegedly racked up 1GB of cellular data on Saturday (according to my online AT&T account). I was streaming the Ryder Cup coverage to my iPad that day, but was doing it over my home wi-fi network and not on the cellular network. The usage data (found under Settings>General>Usage>Cellular Usage) said I had consumed 25.5MB of cellular data since upgrading to iOS6 (when I last reset the stats).

I called AT&T and identified the problem. The rep insisted that the issue was mine and that I couldn't have been connected to my wi-fi network, but nevertheless agreed to waive any overage charges if I exceed my 2GB data plan in the remaining 25 days of my billing cycle.

I asked, and was able to speak to a supervisor to see if they would admit there was an issue. I pointed out that Verizon had already admitted the problem existed for them and pointed him to several reports on the web of the concern existing for AT&T as well. He was polite, but would not admit to any problem...

My recommendation to users on AT&T using iOS6 is to regularly check your data usage online and call AT&T if you see a problem -- they will almost certainly waive any overage fees.

That would certainly be good to know.

My Data Manager does what you want:

but... I just checked and it has disappeared from the App Store and their website doesn't indicate support for iOS6.

A quick search in the App Store didn't show any alterantives with this function.

Just my two cents...but this is a recent chat transcript between myself and at&t:

You are now chatting with 'Nick Cedillo'

Nick Cedillo: I will be happy to assist you today.

Nick Cedillo: I understand you are having issues with data usage. Is that right?

Chet Lewis: thanks, yes - just wanted to add my name to the growing list of customers who have noticed enormous data usage stats since upgrading to iphone 5....Spoke with Apple and they advised they are aware of the At&t data issue and are working on it but I needed to let my carrier know I was also aware...

Nick Cedillo: Ok thanks for that information. I will make a note of this on your account. Apple should be releasing a software update to resolve that issue.

Chet Lewis: very good....thanks for your assistance Nick....

Mine's been draining data since the beta on my 4S, now that it's released, I still see the same issue, and even upgraded to the iPhone 5. Data still draining. Updated my wife's iPhone 4 to iOS 6 and she keeps getting overage charges as well.

I'm going to call the problem a "promiscuous app" problem; If not that, then it's an AT&T problem. In an effort to find the "cell data drain", I have had my cell data OFF since early last night. AFTER I turned it off, I was still draining data, albeit at a slower clip.

According to my AT&T account:
