Look at the size of the United States and look a the size of Western Europe…one is one country, the other is multiple small countries packed together. There’s a reason one of these countries has low passport holders when there’s really no reason to get one. Tropical beaches, frosty mountains, colorful autumn leafed forests, the largest amount of freshwater lakes on earth, etc all within the same borders. Pretty sure you won’t find palm trees in Switzerland.
While I like the idea of a physical SIM, eSIM is nice in the sense that you, or the provider, can just lock/wipe it from your phone with zero issues. Even better, they just remove it from the lost or stolen device and put it on your new one. That’s a nice feature for sure!
