I rarely use my cellular data plan on my new iPad. I try to use wifi almost exclusively. However, some months my 2GB plan is used up and I have to turn off cellular data until the next month's billing cycle begins. Has anyone else experienced this? I cannot figure out what app could be running in the background consuming this much bandwidth quietly on its own. I also have noticed that occasionally when I turn off cell data something turns it back on and I get a warning message about running out of data on my plan. I guess I could call Verizon to investigate this, but I am also curious if other LTE users have noticed a similar issue.
