I have an iphone 6. And in the last month I see these strange data charges. I call them strange because they are very precisely in 20.00mb increments on my bill, ranging from 20 to 100mb. And that is not consistent with any of my known data usage. Anyone know what is causing them?
Reset your data usage calculator or download one from the app store that monitors data usage monthly and keep track of what's using how much data and see what might match up. We can't tell what's using how much data on your phone.
