If you are on a limited data plan from your mobile network provider, then GlassWire can show alerts when you are about to use up all the data from the limited plan. By default, it alerts you when you are about to use 90% of the data. But you can always customize when the alert is to be shown. For example, if you have a 10 GB data plan from 4G network, then it will show alerts as soon as you finish using 9 GB of the data.
