    Actually, this could get interesting. The reason I switched to the 200mb plan is because I'd only used 360mb of a data in a YEAR. I really don't use the network all that much. So wouldn't it be funny if my data usage--which was only 30mb a month while I had unlimited data--suddenly, inexplicably jumped as soon as I signed on to a plan that charges for overages? Even though I'd obviously curtail usage even more now? Basically this plan allows for about 7 times my average usage every month. There would be no reasonable explanation for any overages. My, MY how interesting that would be!

    But yeah, my phone is busily sending and receiving data as I type, even though everything is set to off. Notifications off, all apps are set to do nothing automatically (as far as I have been able to set such options). It would be nice to know just who my phone is communicating with, and why.

    "I have a theory about this mysterious early morning data usage. I too closely examined my past billing statements in an effort to justify adjusting my plans to 2GB/month. It is my belief that AT&T is making an effort to consolidate data usage listings (intentional ambiguity?)."

    Lawrence Fish responded:

    "The problem with that hypothesis is that I would expect that consolidated entry to be at the same time (approximately) every day. But it isn't. If the phone is off at the time it would normally appear it doesn't show up until the phone is turned on again. *_If it were just the billing system posting a summary it would not have to wait until the phone was on_.*"

    My thoughts are:
    Mr Fish is assuming that AT&T is keeping track of data usage during the day and posting it during the night. What if the phone is keeping track of data usage during the day, not AT&T, and the phone is sending out the total during the night?
  • Joo Chung Level 1 Level 1 (10 points)
    Well.... I just reset my call / data statistics on my iPhone 3GS. Not sure if anyone else has yet confirmed whether the usage data reported by the iPhone matches the usage data reported by AT&T's bill. So... this at least will tell me if the two corroborate each other.

    I guess that's possible, but as an engineer I would never design the system that way. First, any decent hacker could find a way from keeping the phone from reporting actual data, and second, if the phone were destroyed the last day's data would never be billed. Then I've also noticed that the amount of data billed is not always the same as what the phone reports. The billed amount, especially when roaming, is higher.
  • jstewa348 Level 1 Level 1 (5 points)
    Is it possible this usage is due to an app? I have an iphone 3Gs with only a couple of apps (Weatherbug and Star walk) and do not have any early morning data charges on the phone. I have just the small individual charges throughout the day. I am currently on the unlimited plan.
  • Lawrence Finch Level 7 Level 7 (29,465 points)
    If we were running OS 4, possibly. But OS 3.x does not allow multitasking, so unless you put the phone to sleep without going back to the home screen apps cannot run.

    Safari can, so if you leave a Safari page that auto updates open it can use data. So can the Maps app and the email app. I think the built in weather and stock apps can update on their own also, but I'm not sure.

    The problem here is that the 2-3AM data shows as Sent, not Received.
  • Joo Chung Level 1 Level 1 (10 points)
    Lawrence: my records show that ALL data usage is "out". Only the SMS messages seem to distinguish between IN and OUT.
  • noghbaudie Level 1 Level 1 (0 points)
    I just noticed this data transfer a couple days ago when I was thinking of switching to the 200MB plan. I looked over the past few months and saw my usage jump from 150-200MB to 300+ starting in April. Here is the mystery data for this cycle:

    06/08 02:40 AM phone Internet/MEdia Net Sent 2353KB
    06/07 02:23 AM phone Internet/MEdia Net Sent 3333KB
    06/06 02:24 AM phone Internet/MEdia Net Sent 5517KB
    06/05 02:36 AM phone Internet/MEdia Net Sent 7260KB
    06/04 02:47 AM phone Internet/MEdia Net Sent 5941KB
    06/03 02:32 AM phone Internet/MEdia Net Sent 778KB

    I was sleeping during these periods. The data for last night has yet to show up. I have turned off all automatic syncing in apps, and just killed all push for email; now they are set to manual. I will not switch plans until this is solved.

    The next step is to set my phone to Airplane mode before bed, then re-enable it in the AM and see if it still 'phones home' when it comes back online. I am not paying for data that I did not use. If this is a 'consolidation transfer' then why is it one-way? And, if so, why can ATT not give a definitive answer on this mystery usage?
  • Nathan Goldshlag Level 1 Level 1 (100 points)
    I opened a case with AT&T about this. In May this nighttime data transfer was a full 210 MBytes out of 533 MBytes. AT&T closed my case. I asked why, and I just talked to a tech support manager at AT&T who said that it is Apple doing these transfers, they will be billed to the user, and that they are working with Apple. There was an option way back when the phone was activated to allow Apple access to it and apparently there is no way to turn this off.

    I suggest everyone call (800) 331-0500, first menu hit 0, second menu hit 1 to talk to an Apple rep and open a case. I just did that.
  • LaurieNY Level 1 Level 1 (5 points)
    My "overnight mystery transfers" are the opposite... more than twice as much received than sent.
  • Nathan Goldshlag Level 1 Level 1 (100 points)
    My bill does not say sent or received, just data.
  • LaurieNY Level 1 Level 1 (5 points)
    I'm talking about what my iPhone says... since I only reset the statistics to zero 12 hours ago (when my new billing period began), I can't yet see what AT&T says on the bill and I never had reason to look until now. And I will, as soon as it's available.

    Phone is still sending and receiving data. So the mystery activity isn't limited to the overnight hours. Whatever's going on, I don't see why we should have to pay for it, especially now that some of us have capped usage. I agreed to pay for the network data I use from now on, and I haven't used the network at all since my capped-usage billing period began. Not a single kilobyte. Yet my phone shows data usage anyway. Yeah, this is a problem.
  • Helen Darmara Level 1 Level 1 (5 points)
    I have the same issue, two different calls in to AT&T. Told it was "apps doing something." Actually, that was our hypothesis, not actually something that the AT&T person suggested.

    The AT&T rep said, "Only Apple can tell you what the apps are doing." Oh, and "If you turn off data roaming you won't get updates and the apps will freeze up."

    I don't have regular cell coverage at home (and not much 3G within a 2 hour drive, mostly Edge). Last month, I got a 3G Microcell - one of those things that plugs into the router to provide cell service. It works.

    But now, my cell usage went from literally nothing (5 mb tops per month) to 50 mb, 8mb of which are these late night charges.

    At Apple, I found two great reps, neither of whom had run across this yet. The second level one is sending in an engineering report. And I passed on the info from this thread to him.

    When the phone is set up like this:

    Airplane mode ON
    WiFi ON
    Location services OFF
    Fetch Hourly

    I don't get the late night charge. I haven't been able to tell if I get one when the phone first wakes up.

    Today I'm trying this:

    Airplane Mode OFF
    WiFi ON
    Data Roaming OFF
    Call Forwarding ON
    3G ON
    Location Services OFF
    Fetch Manually

    I'm going to reset the cellular data usage, too and see if any data gets sent.

    I notice that when I wake the phone from sleep, the phone first finds the micro cell (the bars appear), then finds the WiFi (the icon is added). So, tomorrow, I'm going to turn 3G off and see what changes.

    I have been following this discussion with interest as I have been having the same 02:00 "Internet/Media sent" charges which account for the majority of my data usage. I did "open a case" with Apple as suggested in a previous post, and Apple states that it is AT&T that is reponsible. I don't have time to do this right now, but hopefully later today I will call a tech guy at Apple directly and then we will call AT&T together and hash this out. Should be interesting. I'll let you know if they figure anything out.
  • noghbaudie Level 1 Level 1 (0 points)
    So I just got off the phone with ATT, and the rep told me that it is Push and Fetch talking out. I told him I turned those off this AM already, but I won't see the results till I wake up tomorrow. So I'll report back tomorrow if that worked.

    For those that need it, here's how to turn off ALL Push/Fetch:
    Settings >
    Mail, Contacts, Calendars >
    Fetch New Data >
    Set Push to OFF
    Set Fetch to MANUALLY

    Then tap Advanced (at the bottom) and individually set all accounts to MANUAL.

    As a side note, I forgot that I had iCal syncing to my Google Calendar since I have been using Pocket Informant for this. I deleted the sync for that while in the settings.

    Hope this does it.
