Q: Cellular Data Usage While Only On Wireless?

Today I got a warning that I had only 20% of cellular data usage available at less than halfway through the billing period. (AT&T)

 

1)  I have not used cellular data (3G) in weeks, connecting since then only via wireless in my house.

 

2)  However, I just checked and I did leave the Cellular Data (in Settings) switched to ON. 

 

My question:  Is it possible that some data use was occuring over cellular, even though I was connected via wireless?

 

Follow-up: Is there any way I can access daily/hourly data usage by connection type?

 

Thanks.

A:

Overnight or while your iPad is dormant (but powered on), while not actively using WiFi, it may use cellular data.

 

I'm pretty sure Apple does not supply a way to access daily or hourly use by connection type, short of looking yourself every hour and tabulating the results.  But your cellular provider may well provide a detailed log of when you accessed their data and how much.

    Thanks!  I guess the question is, what changed?  I haven't altered my iPad usage (original iPad purchased brand new when it was released) at all.  So if anyone knows how I might begin to troubleshoot what has caused the sudden jump in "sleeping" data usage, I'm all ears.

     

    Also, will turning off Cellular Data in settings prevent all data usage?

    This article explains some of the big cellular data consumers:

    Yes, turning off cellular data in settings (or turning off your iPad) will prevent usage.
