SIM type Hybrid Dual SIM: "The mobile phone has 2 SIM slots. The user has the choice of using 2 SIM cards at the same time or one SIM card and one SD card (memory expansion) in their device." So no.

The usual repair companies don't dare (I broke the back, for example), but if an order is placed via Digitec, it is possible. Samsung Pay will not work because Hong Kong was specified as the location via IMEI. The device may come up with Chinese menus after the first start-up.

Yes, the slot is a hybrid slot. Either 2 SIMs or 1 SIM and 1 microSD. No, there is no 64GB variant.

Yes, that is possible.

Yes, that is possible.

Yes, without any worries

Yes, I think so. 2 Sim or 1 Sim with 1 microSD http://www.dualsim-handytest.de/wp-content/uploads/2016/01/samsung-galaxy-s7-test-dual-sim-slider.jpg - There are some 2 Sim with 1 microSD things online.

They are. BUT: In the sim card management, only one of the two slots can be selected for 4G/3G, the other is then set to 2G. This means that one card has full data functionality and the other only telephony/SMS.

It is a hybrid slot. You can use 2 Nano-SIM or 1 Nano-SIM with a microSD card. But not all 3 at the same time.

Yes, the information is correct.
