And I wonder where / how to buy a modification from China with two physical SIM slots
What is the point in two sim cards?
As for me - this is a completely useless thing, BUT ... the conversation is not about me.
Do you know that the iPhone is a special mode of operation for a pair of SIMs? He has 1 communication unit. Sims, in fact, "switch" in turn. Therefore, if you speak one number at a time, for the second one you are unavailable. It is inaccessible, and not busy ...
Appropriately - the same troubles with the network and other things.
