1 month unlimited internet temporarily?

I have a little problem and I've moved into a new apartment since 02/01/21 (everything was very short-term) and therefore I don't have internet yet (it won't come for a month). Now I would still like to watch netflix or youtube on my television, but I don't know how I can temporarily have internet.

If someone knows a possibility, I thank genre in advance.

Have a look around here:

Surfstick probably (?)
