Question about Samsung Galaxy S20 Ultra 5G

Mediamarkt has it in its online shop and Brack.ch has it in its online shop.

At the moment, unfortunately, only exclusively with Sunrise. The ridiculous thing about it all: Only in conjunction with a subscription! I wonder what the whole thing is about!

Brack had once offered it online and for sale, but had to remove it at Samsung's request. It will be offered for sale around May, Brack said.

The problem is if you already have the samsung s10plus with 512gb and 240gb of data on it, how do you want to use the smart switch to transfer all the data at once? since I don't have a memory card with the s10plus, it's a bit tricky. greetings

in advance only exclusively via sunrise i believe
