Question about Nebula Capsule II

As Cryingsmurf writes: Connect to WLAN, install the BlueTV app on the Capsule and watch Swisscom TV. Works fine. (However, I think the app costs CHF 5.00 per month, at least that was the case until recently).

Or do it like me:
Set up a hotspot on your mobile phone, connect the beamer and then you can stream.
Without cables and additional costs

You can connect your mobile phone to the beamer via HDMI and watch Swisscom Blue TV. All you need is a small HDMI adapter for your mobile phone.

Beamer runs a full Android. In this respect, you can use all the apps as you would with a mobile phone.
