    Sounds reasonable.

    Here's my bill: http://files.me.com/michael.seth.novick/wtnkrv

    It's definitely catching every 3G session I have with the phone. So it definitely doesn't explain the huge 3G data bump at 2am.

    But you still don't know that's not your data. Until you can account for the late night items as being additional to your daily usage, it still could just be deferred reporting regardless of how many sessions are listed.

    I've had my iphone 2G almost since initial release (winter 2007). I've always noticed these "odd" data charges that occur in the middle of the night. For me its always between 2AM-3AM usually at 2:37AM. I dont use a lot of 2G since its so slow. If I'm not on wifi I generally dont use data. I've never really cared about these data transfers because the data was unlimited, but I am curious as to what they are. During an average day I'll have several small transfers of 10-30KB then a big fat one at 2:37AM thats always over 1MB and up to 8MB. I, too, have called AT&T and Apple and gotten nowhere, nobody knows what these odd transfers are.

    This has to be a data reconciliation method by AT&T. Here's the entries from my bill. I've snipped out the ones during the day and only included the overnight (1am-3am) entries.

    Adding all these KBs total up to what I'd expect for my usage. There's one every night of my billing cycle. I don't think there's anything surreptitious going on here. It just looks odd because of when it's happening. I can clearly see that pattern my usage in these stats.
  • Eddie Strauss Level 3 Level 3
    Why is ATT clueless about this? Their response to me, twice, is that an App is sending out information in the middle of the night. While asleep. With a home wi-fi network. And they have no power to stop it.

    Shouldn't they be telling me that's my accumulated data usage summarized in one daily entry?
  • TosaDeac Level 1 Level 1
    I agree. I was told it was maybe my visual voicemail. Really?! I would think they have to come up with a better explanation since so many of us are noticing this and bringing it to their attention. They brought all this upon themselves by changing from an unlimited to capped plans, so they better find a good way to explain it to all of us!
  • michael.seth.novick Level 1 Level 1
    Exactly. That's my point, too. I'd be fine if it was clear that the nightly usage is a daily accumulation, but if AT&T doesn't know what it is, then that's a problem.

    I have really minimal cell data usage and I can't understand how "billing data" can be multiple megabytes every single day.

    One experiment I can try:
    This evening, I'll reset my Cellular Network Data and will refrain from using the phone. In the morning I'll check the usage to see if the "unexplained transfer" has been recorded, then I'll check on AT&T's site to see if the same data use shows up. The numbers should match.
    From analysis of my data it looks like the 1am transfers occur regardless of whether I use the phone for the day or not but I suppose I could try shutting off the phone after the 1am transfer for 24 hours, then turning it on. I suspect it will "transfer" when turned on, even if there was no usage for the previous 24 hours.

    This really doesn't really help me out though, it doesn't explain anything. I think the next step is to find a GSM access point, repeater or cell-to-internet rerouter w/logging to install at home. Maybe then I can get a look at what the data is.

    Here a few thing things I've 'learned' from AT&T over the years talking to the sales associates in the store or calling tech/customer support: When the iPhone battery dies you throw the phone away and buy a new one. Apple didn't make the iPhone, it was licensed from HTC. It isn't possible for me to have an AT&T account because I live in an area that has no AT&T service (I could see the AT&T tower from my apartment and my community had been in AT&T service for at least 6 months by then. I had to get my first AT&T account using my business address!) My Motorola phone would only work with accessories bought from the AT&T store.

    So if the AT&T rep you talk to claims to be clueless - believe it.

    Some thing else I'm going to try. I think I'll keep the iPhone plugged in and disable sleep - that way the wireless will be available all the time. If the data transfer uses the wireless it will log in my router, if it still uses the cell data - that would be fairly suspicious.

    Greetings All,

    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?). For example, reference my usage for this month to date:

    06/07 01:10 AM phone Internet/MEdia Net Sent 31894KB
    06/06 01:44 AM phone Internet/MEdia Net Sent 12044KB
    06/05 01:02 AM phone Internet/MEdia Net Sent 18012KB
    06/04 01:02 AM phone Internet/MEdia Net Sent 13473KB
    06/03 05:36 AM phone Internet/MEdia Net Sent 13967KB
    Total this page 89390KB

    Throughout the day I retrieve emails, browse the internet, and use data within various applications. My data usage throughout the day appears to be condensed into one daily data usage. Could AT&T be using early morning to let their servers crunch data usage into one accumulated value? If this is not the case, do our iPhones phone home first chance they get connected each day and report usage?

    ** I understand there are also individuals with data usage being reported throughout the day and each morning. Could specific data usage (per apps) be collected separately for statistical analysis? Who knows Apple Secrets.

    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.

    ** I understand there are also individuals with data usage being reported throughout the day and each morning. Could specific data usage (per apps) be collected separately for statistical analysis? Who knows Apple Secrets.

    If you are connected to a WiFi network during the day (as I am for most of the day) you will have no data usage that AT&T sees.

    Right . . . and in addition this would beg the question, why are some data connections listed individually while others are lumped together into a single late night pseudo-connection? It doesn't make sense.
  • LaurieNY Level 1 Level 1
    Nice to see I'm not alone. I just switched to the low-usage 200mb plan, and my new billing period started at midnight. So I reset my stats at midnight. I've been completely on wi-fi, I have nothing on push, bluetooth/location services off, 3G off. Yet data is being continually being sent and received. Every time I look, the numbers go up. It's 12kb so far in about an hour and a half, even though I haven't used the cellular network AT ALL.

    Now it's at 18kb. In the time it took to type this post.
