I may amend that for an additional CHF 5/month you can also get 250MB of data valid only in Switzerland (so-called "Surf Start") and for CHF 50/month there's the "Unlimited Surf Roaming" option which gives you unlimited data in Switzerland and 500MB for Europe (source:

So you end up with CHF 90 or CHF 135 per month.
