Goodmorning!
No need to apologize. English is perfectly understandable
About the Philips 55PUK7100/12, the list that Ziggo shows on their website is far from complete and not updated on a regular base. This is a shame, because when this would be the case, it could save a lot of worries and questions.
The information that I can find about the 55PUK7100/12 on the websites of reliable webshops like Coolblue and the tech-site Tweakers is that this model DOES support CI+ for Ziggo.
Just to be sure, you could contact Ziggo or the webshop you want to buy the TV from.
