Things to know about Up to 4k UHD video

• Activating Up to 4K UHD video resolution only provides the ability to view higher resolution video streams by turning off video optimization. It doesn't change the actual, available resolution of streaming video. The 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, Up to 4K UHD video streaming availability should take effect immediately, but it may require closing and re-opening the app or browser window, or restarting your device.
