These are the US carriers that let you stream at HD resolution or higher

While limited data plans still exist, unlimited plans have become much more prevalent in the US market over the last decade or so. Unfortunately, not all unlimited data plans are created equal. Many carriers only provide so much high-speed data before the line is slowed down in priority or even capped at a slower speed that ranges from unnoticeable to unusable. The most common limit you’ll find is on streaming quality, with many services limiting the quality to just SD (480p.)

Are there any US mobile plans that offer no streaming throttle, or at least all give you the option to adjust your quality settings? Yes, actually, there are several options on both the postpaid and prepaid side of the market.
