I have 5GB of data and am constantly finding myself going over... By a lot. We don't have wifi. I have most of my apps data turned off. And I also turn my data off when I'm not using it. What am I doing wrong?
Since you say you don't have WiFi, that's probably your problem. Phones are poor substitutes for home internet. I realize some very rural areas have difficulty getting reliable Internet service but you should definitely look into who provides Internet in your area.
