As I told you before, replace the mobo from a broken one, may you're lucky at the bay. Mostly the SIM is build together with the mobo.He showed me and I saw. It has slot for two SIMs. Also, there's a long discussion here on xda and reddit about it. A guy printed a 3D dual SIM tray for 6P and bricked the device. Honestly I don't know anymore what can be done to fix my device.
