Not downvoting, but any typical online activity during commute or while travelling will blow through 1GB. Music every day, or a video once in a while…

I also have WiFi at my usual hangs, but thus far this month I am on 15GB of my 50GB monthly plan. Sure I could pre download music or videos to watch, but it would be much more of a hassle. And some sites, like twitch, don’t really have an option to download.
