Valve has announced Steam Link Anywhere which allows Steam users to stream their games from their PC to their other computers over the internet or Wi-Fi, as long as their computer has good upload speed and their Steam Link device has a good network connection. I confirmed that I could stream from my gaming PC to my mobile phone using mobile data. This service is free and the Steam Link (BETA) app can be downloaded from Google Play. Steam users will need to update their Steam Client to the beta build to enable the functionality. To use Steam Link Anywhere: Update your Steam Client to the beta build, dated March 13 or newer. Add a computer and select "Other Computer." Follow the pairing instructions on screen. This service is in early beta, and we appreciate your patience as we continue to improve the service.
