also mobile plans are cheap in Switzerland. You can get a plan including unlimited calls throughout most of Europe+Canada+US (incl. roaming) plus unlimited 5G in Switzerland plus 40GB of data roaming throughout Europe (not only EU)+Canada+US for 35-45 CHF/month. These are sales that happen 3-4 times a year, e.g. via qoqa.ch or on wingo.ch. I have two of those from two different providers.

Regular prices for such plans are CHF 100-130, which I also do not find overly expensive compared to US.
