Dish’s internet TV service Sling TV added support for Google’s Chromecast streaming adapter to its mobile apps Tuesday. This makes it possible to start live TV streams from Sling on a Chromecast-equipped TV straight from any Android or iOS mobile device.

Sling is promoting the launch with a device deal, offering new subscribers a free Chromecast streaming adapter if they prepay for three months of its service. Sling is also offering existing Chromecast users a two month free trial. That free trial can be accessed through the Chromecast website, or Chromecast’s mobile app. However, users have to be on the same home network as their Chromecast adapter in order to redeem the offer.

Sling previously launched its service on Roku, Amazon’s Fire TV, Xbox One and Google’s Nexus Player. The service offers users live streaming of a select and customizable package of cable channels starting at $20 a month.

Dish executives revealed on the company’s last earnings call that Sling had 169,000 subscribers at the end of March. We may get some new numbers when Dish reports its Q3 earnings next month.
