I was really hoping they released this with dual Sims. Currently I have a Oneplus One as a main line and I need to get a second phone asap. I'm hoping there could be some sort of mod we can do to change the Huawei to dual sim. Huawei has a lot of dual sim phones so I'm assuming the hardware comes already pre-wired for it.
I'm hoping to find a way not to have to carry my Oneplus One and a Nexus 6P. Both phones are pretty hefty to carry especially in a suit. I understand the phone is not released yet but let's get the ball rolling.
Update Nov 18 2015
Is it even hardware capable?
Yes, it is actually. Have a look here at the teardown by ifixit.
What about the sim tray?
It is able to hold 2 nano sims by default. The only issue is there is a bar blocking the second sim slot. You are able to bypass this by using a dremel tool and cutting it off. If you're not that handy there are some users here making 3d printed trays. This will be updated once someone is willing to supply the rest with working trays.
What about the IMEI for the second slot?
It can be set to 0 and used as such. It has been done in various other devices.
Isn't setting the IMEI to 0 illegal?
Check your countries laws. USA = NO
Sim Tray Variants
You can use a dremel on the metal one and pop the sim card in. It has the slot ready only thing it's blocked off by a thin metal bar.
