With the CH version or SWISSEDITION, the 4G network works for me, which was not the case with the EU version! After a few phone calls with Samsung, this was also confirmed to me by phone. So it is a difference in network strength of 0.1. In my opinion, better buy a CH edition, the choice is up to the consumer. Best regards

The hardware is the same. There is only a difference in firmware, i.e. software. Some services, such as Samsung Pay, are not available in the EU version.

Unfortunately I can't tell you that the phone was a present for my sister but she really likes the phone and was really happy about it so there are no big differences.
