The iPhone uploads diagnostic data to apple every once in a while, normally at odd times in the morning. If it is in sleep mode the wifi is turned off to preserve battery, and while AT&T allows this usage for free, T-mobile is probably charging you for it. That's my guess and I'm sticking to it.
 
Your phone service cannot see what your are using via WiFi unless it is one of their WiFi networks. I have AT&T and I occasionally disable my cellular data to keep me from going over my megabytes. I have found this to be a very cheap alternative to going with their 2GB data plan, I can now go a month with only using 200MB of data. :)
 
200MB of data a month sounds painful lol. I used 600 some MB last month and I'm usually on Wifi.

Anyway if I were to switch to T-Mobile I would get the 69.99 everything plan. What's the point of having an iPhone without data? Although it must suck since iPhone can only do edge data on T-Mobile.
 
Ok I called and this time the lady was very helpful. She actually said YOU can turn off pay per use on the phone and there wont be any chargers with the iphone.

HOWEVER, she said if I didn't have that there are chances that while I am using wifi because the iphone like to use the internet it automatically turns the pay per use on and they can't do anything about unless I call and restrict the phone from activating it by it self.

So we will see next month if I get any chargers.

There is a way to turn off Celular Data. It is in the Settings menu, then General, then Network. Cellular data should be off. And, if you're paranoid, turn off 3G right above it. 3G technically shouldn't work with cellular data turned off, but you never know what the Jesus phone can do. :apple:

Also, while this lady may have been more helpful, her comment that WiFi is causing your bill to go up is complete techno-BS. And, the iPhone doesn't switch to cellular data service unless there are no wifi hotspots that it can pickup a signal from. Mine typically will scan for wifi as long as I have that toggled on. When it picks up the signal from my home (& now my buddy's home :D), it switches to that by default.
 
I also turned off 3G and EDGE data service and only use WiFi. So far, my account doesn't show any data being used when I login at Tmobile.com and I've had it for over a month now.

I love TMo, but if they try to pull this stunt with me, I'll inform them that I'm out of contract and they can either remove that charge and keep me as a customer or they can say their goodbyes now. I'll either jump to AT&T or the iPhone or I'll look into one of the new Android phones on another carrier.
 
I can't believe this thread hasn't died yet. Obviously the OP was mistaken or pulling our legs; it's not possible for T-Mobile to charge him for using WiFi. Please, can we let this go?
 
ME TOO!!!! So angry.

I am so glad I found this thread. Last month, I was charged $50 on TMobile for using my own home WiFi!

I spoke to two representatives - one was VERY rude and hung up on me. After talking to the second representative, I was transferred to a supervisor who was no help at all.

Any legal people out there who can give advice on a potential class action lawsuit? I am serious.

As pixelated said, the people you need to contact are lawyers. Quit annoying us. I am serious. Or are you a lawyer trolling for clients?

I have as much of a right as anyone to ask a simple question. I was merely trying to find out what the outcomes were for other people with this problem. You did not have this problem and yet you are trying to interfere with others that do. Just don't follow this thread if you consider it an "annoyance." Simple.
 
Ha! "Jesus phone". Sure...more like "Jesus Christ I can't believe this piece of s**t phone dropped another call."

No, you (and others) were charged for using T-Mobile's network. This may come as a shock to the loyal minions but just because you're connected to wifi doesn't mean it's actually using wifi for everything. There's a considerable amount of data that insists on going through the cellular network. You need to do more than just turn on wifi, you also need to make it impossible to connect to the cellular network, such as giving it a bogus connection point.

Quoted for Truth. There is no possible way for T-Mobile even to know you're using WiFi, much less to charge you for it. If they're charging you for data, it's for data you unwittingly sent over their network.

I'm not on T-Mobile, but Ive used the unlockit apn changer site to block data on my son's iPhone. His network shows fake APN or something like that.
 
Hi

I also have an iPhone and the exact same thing happened to me.
I'm on a prepaid plan and for some reason, the credit dropped from some 800min to only 185min. Apparently, like the whole apn thing said in the previous post, push email or other stuff may be using the data. It doesn't even need to use 1mb, as long as you connect to the data line, it starts charging money.

No, I don't think they can charge you for using wifi, because isn't that illegal? They have no control over your device or using wifi, so it's not reasonable for that to happen.

You can install Data Disabler from Cydia to stop data usage. Also install the data toggle for SBSettings. Or you can upgrade your phone to 4.0 which has a built in setting to disable the data usage. The 4.0 option would be the best, because it survives resprings and restarts(the cydia option sometimes doesn't survive restarts). THe 4.0 option is also reliable, since it virtually turns off the data part of the phone

It has nothing to do with wifi; the OP got false information from a T-Mobile customer representative and, instead of actually doing some research, came here spreading even further false information. You may be on the right track with your other thoughts, though.
