check if the LG Smart TV model is compatible with the blue TV App
blue TV App: New on LG Smart TV and Quickline TV box | Swisscom Community
The blue TV App will be available on additional devices from 31 March 2021:
LG Smart TV
LG is the second manufacturer after Samsung to enable the blue TV experience without an additional TV box. The blue TV app is available on LG Smart TVs from 2018 onwards.
If you have an inOne Home subscription with TV, then you have included use via a TV box in the subscription. If you now want to use blue TV on other TV devices (directly on Smart TVs or using TV boxes), it costs CHF 5 per stream. This gives you access to your stations, recordings, etc. on multiple devices.
If you no longer want to use a TV box at all, you would have to adjust your inOne Home subscription and remove the TV there. Then you could log into the app and decide whether you want to use blue TV Air free (with advertisements and no additional functions) or blue TV Air as a subscription. It has some additional options, but of course not the possibilities and options as with the TV box usual. More information here:
