HD video resolution details

• Activating HD video resolution only provides the ability to enable higher-resolution video streams by turning off video optimization. It doesn't change the actual, available resolution of streaming video.
• Video resolution isn't determined by T-Mobile, but rather it's determined by the video content provider like YouTube or Netflix.
• Once you turn it on, HD video streaming availability should take effect immediately, but it may require closing and re-opening the app or browser window, or restarting your device.

Full terms

All on-network data used, including free streaming data, counts toward the heavy-user threshold of 50GB in a billing cycle, after which a T-Mobile-branded customer will no longer receive highest priority on the network. When an HD video is active, streaming high-definition video will use data much faster than optimized video, and brings up to the possibility of de-prioritization if you use enough data to reach that limit in a given month.
