The result: I've had to completely turn off cellular data for web browsing.
I can use mobile apps fine; chess.com, slack, telegram, email, etc. Streaming even pandora is out, but luckily they have an offline mode that allows you to download your station when you're on wifi and then play back whenever. But I can't browse the internet at all.
I'd be willing to spend up to $50 a month for a limited package, but at most that seems to get me is 1-2GB when I'm in Canada unless I want to sign another long term contract.
Every page i download, every news article, easily 2-3MB, and when your total data allotment is 500MB, you just can't browse the internet. Even hacker news, a popular post ends up being 1MB worth of comments.
