Certain features may be limited or unavailable on an EU model in Switzerland, such as VoLTE, WiFi calling, Samsung Pay and other services. Also, EU models are not eligible for cashback or other promotions in Switzerland.

Indeed: With the EU version, Samsung Pay cannot be used in Switzerland because no Swiss address can be entered!
Well, who would have thought that possible!
Does öbbe öpert know a workaround to still be able to use Samsung Pay?
