Can I use blue TV and blue Sport with yallo TV to watch, for example, Champions League or Bundesliga?

The TV Box you receive as part of your yallo TV subscription is an Android TV Box with access to the Google Play Store. If the game is not broadcast on Free TV, you can download the corresponding app (e.g., blue TV or Sky) from there and watch the game through one of these apps, provided it is broadcast there and you have the appropriate subscription.

However, we would like to point out that yallo is in no way responsible for the content and subscriptions of blue TV, blue Sport, and Sky Sport, there is no collaboration, and we cannot provide information about these providers.
