iPhones are expensive things. However, in Europe, they are even more expensive than in the USA. Is buying an iPhone in the US, to use it in Europe, a good idea? The US iPhone XR (model A1984) has one LTE-band missing (number 28), that the European model (A2105) has. All other bands, about twenty in total, are present in both devices. Does this really matter, I'm asking myself. Anyone who knows?
