Crazy Data Usage - 69 MB in just one day?

I bought my mom an iPhone in Canada when the 3G came out and last month she travelled to the USA to visit her family. SHe asked me if she could use the data plan there and I told her to use it sparingly because it costs 1 cent per kilobyte. He said she would not open any attachments or browse the web, she was only going to read and reply to important text emails. If figured it most cost her $30 or $40 for her week long trip.

My mom is no technophile. She uses email incredibly sparingly, and doesn't even know how to download applications or download music or pretty much anything else.

So end the end, when she got back from Atlanta, she told me her bill was $800! She says she only checked her email once or twice per day and only downloaded important messages which had no attachments.

I just got a copy of her bill today. Most days it looks reasonable. 100 kb - 400 kb per day.

_*Then there's one day where she used 70 MB in one day!*_ Her charge for that single day was like $400.

What could she have possibly done that would use 70 MB in one day by only reading emails. Her mail account quota is probably less than 70 MB and she only read NEW messages with no attachments. She probably doesn't even regularly use 70 MB of email storage/bandwidth in a month! Is there some sort of bug that could result in runaway data usage? After that day there are a few days where she uses 10 MB per day, which also seems unusual but not as crazy as the 70 MB day.

I looked back at my bill from AT&T over a week when I had no wifi access. I am a heavy data user, and I only used 30 MB per day max. And I was downloading applications, using safari, emailing photos, basically using my data plan to the max (good thing it was unlimited).

Does anybody have any ideas about where this ridiculous charge could have come from, and how to prevent it from happening again? The worst part is, she obviously didn't know she was using that much data. I told her 70 MB is the equivalent of downloading 350 large photos (200 kb jpegs) and she said she didn't even download one single attachment.

Is it even possible to contest this charge with Roger's

Thanks for your reply. That's what I was thinking. It seems like some sort of bug or issue with the phone's data connection because it should not use that much data in one day. It would actually be hard to use that much data even if I tried.

I looked at some of my own personal data usage rates while traveling away from wifi (such as my grandparents house, same place she was when she got this charge). In general, tend to use the internet a lot more than she does. I have a lot of applications installed, I send photos and attachments, I use a lot of internet apps (facebook, mobile chat, etc), and I use Safari a lot.

I wasn't trying to limit my data usage becuase I have AT&T (unlimited), and I ended up using about 30 MB per day. So in comparison, if she was trying to limit her data usage, not browsing the web and not running any applications (she doesn't even know how to install applications), you would think her usage would be less, not more than mine.

I hope we can get this charge reversed. I've disabled her data roaming in the meantime.

Did you check the usage indicator in the phone to see if there are any discrepancies. Of course if it hasn't been reset recently it'll be pretty meaningless.

I agree, I can't even imagine how one can get through 69 MB in a day, I only use max 20MB a day even with listening to internet radio on the way to work. I don't think any bugs on the iPhone's part would cause this.

Definitely call rogers, they can give you a breakdown of usage on that day down to the exact minute. Ask them to check how long it took to accumulate that much data. If it's like say within a few minutes, then you'll know it was a bug on their part.

They told me that at exactly 12:29 pm she used 38,384 kb all in one shot. Then at 12:59 pm she used another 8,025 kb, etc. He had to read me each individual charge because they are not included in the Roger's bill like they are in the AT&T bills, so I don't have all the details, but even that 38 MB all in one shot seems pretty weird.

Unfortunately, she didn't reset the data counter before her trip. I should have told her to do that.

I just checked my usage and when I was out of town and using 100% 3g data I used about 30 MB in one day (that was my max) and I used more like 20 MB per day average. That's with extensive web browsing, chatting, email, etc.

The other weird part is that on average, according to Rogers my mom uses 60 MB per month except for this last month where she somehow used 60 MB in one day!

I managed to get all of the charges reversed except $100, which seems pretty reasonable to me. But I am still curious about what caused this ridiculous data usage. My mom is going back to the US tomorrow and I have disabled her data roaming feature. I wish she could use it though, and just try to minimize her usage, but if there is a chance that using mail minimally while roaming could result in another random $600 charge, I don't want to even consider it. She was pretty disappointed in Apple and Rogers that she could not use her mobile data features while traveling for fear of accidentally costing herself $600 for a week long trip.

If anybody has any ideas about what could have happened to cause the ridiculous 69 MB usage in one day or how to avoid this from happening in the future (aside from data roaming) I would appreciate it.

Otherwise, it appears that while the iPhone is the best phone out there for local calling, Blackberry is still the king when it come to roaming. The charge is the same for data roaming with a Blackberry on Rogers (1 cent per kb), the difference being, I've never had a random 69 MB charge on my blackberry when I from minimal email usage. Even the fact that Blackberries use compressed data does not explain why the data usage was so high.

To make it even weirder, when we were going through the bill again, we realized that 40 MB of that 69 MB charge occurred while her phone was supposedly in sleep mode (she forgot to turn it off) on an airplane, most likely during taxi/takeoff. Could that explain anything?

No, she only uses mail.

I did a test myself. I reset my data counters and went on 3G and tested how mch data would be used if she accidentally opened google maps, weather, stocks, loaded a page in safari and then browsed the App store, then downloaded some emails with photos.

In total I used about 2 MB of data not 69 MB.

Of course she never used any of these apps, it was just a test to see how much data I would use.

So although apps use a fair amount of data. I've seen that you will never accidentally use 69 MB in one day and not even know it.

The only way I could think of using 69 MB would be to specifically browse to a website with a large file (video for example, or maybe a large tiff) and specifically download it.

It would seem then that if one wanted to, one could limit their data usage while roaming by not intentionally downloading any large files.

This appears not to be the case though because of this "mystery" data charge.

Rogers has a plan where they charge you $1 per MB instead of $10 per MB while roaming (it costs $10 per month plus the data charges). That seems pretty reasonable to me, as long as she didn't end up using 69 MB per day - then the charge would be $69 per day which isn't very cheap. Thats why I am afraid to use data roaming still, at least until I can explain the mystery charge.

Her email is set up as POP (her server only supports POP). Does anybody know if POP uses a lot more data than IMAP (I use IMAP and my data usage has never been 69 MB in one day).

Does POP by any chance download every attachment when checking mail, or does it only download attachments when clicking on messages.

The weird part is her entire inbox is probably less than 69 MB so even that would not explain the high usage.
