What in iPad could be chewing up my data allowance without my knowledge?

[Vagulus]

My computers (a PC and an iPad Air) chew through half-a-GB of data a day even when I am not downloading/uploading anything.

Does anyone know of anything I might have on the iPad which would be thrashing to that extent?

Thanks

If you are talking about you cellular data, go to Settings > Cellular Data. You can see which apps are taking the most data, and turn off any that you don't feel need access off wi-fi.

At the bottom of the list you can tap System Services to see what system services have been using.

At the very bottom in smallish text you will see a date. That's the date is when the current stats started. You can Reset Statistics to start over.

I can't find anything called Cellular Data in Settings!
Where is this?

It only exists if you have an iPad that can connect to cellular services. If your iPad is wi-fi only, then it won't be there.

There is no built in way to see what apps/services are using bandwidth over a wi-fi connection. I seem to remember apps in the App Store that claim they will do this for you, but I don't know how they work, or how well. And they would only apply to the iPad side of things.
