Vodafone GigaTV Box = TV program?

I recently moved and got to the entry of Vodafone a Giga TV (box) to the Internet contract. Since I have only now a television and would like to know what this box makes. Since I've been standing around for so long, I do not remember what the Vodafone salesman said, the box was free with it. Without further instructions. I'm already considering to get Netflix or something similar, but I do not want to subscribe to something that I would have on other way, so through the box already.

Does anyone currently use such a box and if so, what can one "subscribe" to without hesitation?

To be said:
I have not had a TV in my possession for 10 years, I've looked at most of the PC so that's a little new ground for me.

The Giga TV Box by Vodafone is a 4K receiver with 6 tuners, so you can record 5 different programs simultaneously and watch a 6.

The box also offers many Streamnig offers, Netflix is thus usable

In the box is a smart card, on the smart card, all subscribers of Vodafone are unlocked for 2 months, you must terminate before the end of 2 months in writing if you do not want to use them, otherwise you have the subscription for 24 months, the entire subscription costs 25 euro per month, there are around 30 TV subscribers and another 20 radio station singers included in the subscription, the TV channels all in HD.
