How much speed do video streaming services need for HD quality?

For most streaming services, speeds up to 40Mbps on our Unlimited Data Plan or 80Mbps on Unlimited+ Data Plan is more than enough to stream in HD. In fact, Netflix only recommends 3Mbps for HD streaming, so 40Mbps on our Unlimited Data Plan or 80Mbps on Unlimited+ Data Plan is suitable to be able to stream high-definition video.
