Questions about Apple iPhone XS

Quick question: The iPhone XS is currently on sale at Digitec. The 64 gb version used to cost 913.- and the 256 gb version 949.-. A price difference of 36.-, which is still an acceptable surcharge for more storage space. In the promotion, however, the price difference is now 200.- (649.-/849.-)! How does such a huge price difference come about? That's more than 1.- per gb!

Does anyone know if the iPhone X cases are also suitable for the Xs?

Is the unit in its original packaging ?

How quickly will it be delivered?

Is this phone compatible with SIM cards from mobile operators in Japan?

well. what can i say. the device is fantastic: only with the move of whatsapp i'm going insane. has anyone ever managed to transfer their whatsapp backup from android to iOs? an unbelievably impossible thing... Digitec should do an article about it... while I wait for the next 48 hours to be able to verify my whatsapp again...

Hello digitec community will the Chinese version be available from you as a physical dual sim phone? Since e-sim seems to have some limitations.
