We have gotten it, but with services not websites. Mobile providers will sell you an "Unlimited" data plan that throttles everything after 25GB a month. Streaming Spotify and Apple Music won't count against that soft data cap. Streaming other music services will count against it. Video streaming over YouTube, Netflix, etc is capped at 480p levels. If you pay an additional monthly fee, you get upgraded to "Unlimited Plus" which will increase your soft cap to 40GB a month and your video streaming quality to 1080p. It'll also bundle in Netflix's basic level and give you 6 months of Apple+ for "free".
