+1 for Airalo. Used Airalo recently on a trip to Switzerland. I think I paid 5€ for the cheapest plan and got a 3.5€ voucher that made my wife's eSIM 1.5€. Worked very well the whole time and everything was very smooth. The standard EU free roaming does not cover CH, at least not on my plan, so I needed something like this.
