On my iPhone 5c (Verizon is carrier), I've had it for 2 days, and I got a notification that I've somehow used 934 MB already??? When I look under cellular data by application, (under "system services") it says only 19.5 MB. Help???
Does anyone else have a similar issue that can help me figure out what in the world I need to disable so that I don't end up using 15G a month?!?
