With a 1.2 CI plus module (a non-interactive CI + module) you can simply use the services of Ziggo. In this module you then add the (paid) card that you receive from Ziggo.

If you are looking for channels via Ziggo, the Lenco TVs also put the channels directly in the right order.

It is not possible to watch digital channels without a CI + module and a paid card (for example from Ziggo). There are probably digital channels that can be watched for free, but these are not usually the regular channels.
