Another place to look is in settings -> Data Manager, and select Mobile
to look at usage.  For me, under there are a list of apps that want data
access.  I know there is one app that I set it to "restricted": it only
gets wifi access, not data.  It is a security web cam app that can
generate tons of network traffic.  When I had a limited data quota, that
app sucked it all up in a short time.  Videos consume a lot of quota.
So, I configured that app to only allow it wifi access.  

I used to have the HERE WeGo app for maps which could download a LOT of
map data.  Although I only had it download offline maps for areas where
I live, and where I may travel, those offline maps still consumed
something like 20 GB (configured to store on the SD card).  The
downloads took a long time.  I didn't want to consume data updating the
offline maps.  However, for that app, it had its own setting to restrict
map downloads to wifi (not use data).  I didn't have to go into Android
settings to restrict the app to only wifi access which would not only
apply to offline map updates, but using the map app while moving since
wifi hotspot are limited in range, and there is no reconnect when
leaving one wifi hotspot to moving into range of another wifi hotspot as
there is with switching connections when travelling between cell tower.  

When going to those Data Manager mobile settings on apps, you can
disable background data usage to restrict an app to only give it wifi
access.  Navigation to the similar function on whatever phone you have
may differ from mine.
