I don't understand what eats my data to give me overage. I don't play games, or use apps, except texting and photos, I have facebook but rarely use it or read it, I try to clear and close anything opened

Question

I don't understand what gives me data overage, I make calls, text, take photo or video. I don't use any apps maybe once in a blue moon google a question. no games or navigation, don't shop, I do have facebook, but rarely use it.because I look on computer. I try to clear and close after each use. So what else can I do to prevent something eating data? I am a senior and don't understand gigs etc. Maybe  a few times a month I might post from cell to email a pic.

Just because you do not use an app does not mean it is not doing something in the background.
Facebook, for example... If you have used it one time it can be uploading any photos/videos you take with your phone on a regular basis even if you don't open it up again. Have you checked your settings in these apps to only sync while on wifi. This can cause a lot of data usage if you did not.
If you don't feel you need the app, either delete it or disable it.
Once you open an app the first time, it is activated and unless you make sure the app settings are such that you will not use a lot of data, you should assume they will. Especially apps which have the capability to upload photos/video from your phone.
