Hi
NeilCW Welcome and I can tell you, the answer is no.
It is not possible to use Ziggo Go for 1 month. You have to be a real customer for at least 1 year to be able to use the free Ziggo Go service. What you can do is ask in your area if someone has Ziggo Go and if you want to help with login details.
1 year contract is only if you get a discount with your subscription. If you take out a subscription without discounts, you can cancel every month. You will receive everything at home and that is quite awkward because you cannot connect anything.
I wouldn't take all that effort for 1 month of TV.
Since you don't have a cable from Ziggo it will all be very difficult, I expect.
You can take a look at the NPO start app or the Videoland app or NLZiet app. This allows you to watch wirelessly via the internet and you pay per month.
