I have been paying for 250gb each month from at&t. I had this renewed last Friday. I have cable internet at home that I use with my Ipad when I'm home. I left the Ipad on a table and left(no one else was home) and when I returned 3 hrs later..I had a message telling me I was down to 16%....Cellular data is always turned "on"..I just can't figure out what used it all, especially since it was in range of my home internet service and that service was working fine.
Any answers?

By 16% down you mean 16% of your 250MB were used?

Here is the rub with the iPad, when it is on, it always uses wifi over 3G, but when it is in sleep-mode, it always uses 3G. So because no one was using the iPad, did it revert to 3G for checking mails, etc.

started out with 250MB...3 hours later had 16% left

oh, I didn't know that it uses 3g in sleep mode. It was in sleep mode...but I've never seen it dwindle that fast!
Thanks, I feel like I've just given At&T $15....once again.

But I have the same plan as Pati ~ and my 3G doesn't run down that quick. I never see 3G kick on unless I am out of my house....

Oh but that is strange.

Did you have any audio streaming apps open? It really shouldn't have used that much data in 3h from just checking mails.

You will never see 3G kick in, because as soon as you wake the iPad, will it use wifi again.

no..none open. I had been playing Angry Birds!

Did you remember to turn the cellular data tab off when you were finished using 3G?

I've gotten really frustrated too with things like this happening and not knowing why data has run off so fast without any answers. I found a service that I started using called TruConnect though that lets me use WiFi with my iPad through a 3G connection, so anywhere AT&T 3G works, for $4.99/month and I only pay for the data I use at 3.9 cents/MB. I used only 167 MB last month so my bill was $6.51 + $4.99 = $11.50. This might also solve your problem because you use a MiFi device that you can turn off so independently of iPad so data can't be charged when the MiFi is not on. Also you can connect up to 5 devices using this MiFi so my wife and I use it for both our iPads with only one data plan. It's a sweet deal for us!
