Device restriction for blue TV: what you need to know
With blue TV, as well as enjoying content on your Swisscom TV-Box, you can also watch on your smartphone, tablet, computer or TV. The following article explains everything you need to know when using multiple devices.
You can use up to 5 Swisscom TV-Boxes to watch blue TV at home (with an inOne home subscription). Watching on multiple TV-Boxes in parallel is not a problem, provided there is sufficient available bandwidth. Nowadays, however, you don't necessarily need a TV-Box. blue TV is now also available as an app, ready to download on your smart TV for example. Please note, however, that to prevent misuse, the number of devices on which you can watch blue TV via the app is restricted.
