I would be a lot less worried about signing up for that plan if I could soft-cap myself at 10GB until I login to the app and push a button that says "yeah for real I'm going to use another 10GB of mobile data", so that if iOS goes bonkers and tries to download my entire 90GB iTunes library over cellular, it doesn't fuck me over for a month. I haven't exceeded 7GB/mo intentionally for years, but it's happened twice so far against my express wishes, and carriers are uniformly awful at that.
This is good feedback. We don’t want caps and throttling to be a blocker for signing up and using us. Since we’re at a premium price point we should economically be able to be a lot more generous than existing carriers.
