Unlimited Internet for a week?

I live in Switzerland and go to Germany for a week in a few months. Had earlier always Wi-Fi from the hotel. This time there's a round trip with only a few stops in a hotel. That's why my question is; is there a tariff where I get unlimited internet for a week? Have looked at various providers, but found nothing. My idea would be to get this package in the form of a sim card, so I have internet on my smartphone and also on my laptop.

Looking forward to an answer.

Nope! Unlimited mobile Internet is not available in Germany, or only with a contract (ie 24 months) and then 80 euro.

OK, too bad.

Yes, Germany is truly one of the most backward countries in terms of Internet.

A possibility:

2 MO.

Make unlimited calls to all networks

Surf unlimited

No reduction

SMS / MMS: Unlimited

4 GB per month in neighboring countries abroad

95.00 CHF / month

but are just "only" 4 GB

another solution would be upc WiFree, ie if you are an upc customer or a buddy who has his access data you can access in their wlan nets (unitymedia) but because you have one of their nets in range, that is not really a reliable one either solution

and btw as swiss without address in DE you get anyway no German subscription;)
