Sorry, there was a problem. Please try again later.If they are smart TVs, some have the sling app in app store. If you do not have a TV with access to applications as such It is a Roku device you will need, or a fire stick. Theres no box for sling, rather it is an app. You will need the app/ device per each tv. (Max of 3 depending on your sling package details)
